On top of the page you see the link to the user login page. Copy this link address and give it to your users.

Below the link you can specify several options.

2-factor authentication

LAM supports 2-factor authentication for your users. This means the user will not only authenticate by user+password but also with e.g. a token generated by a mobile device. This adds more security because the token is generated on a physically separated device (typically mobile phone).

The token is validated by a second application. LAM currently supports:

• privacyIdea

• YubiKey

• Duo

• WebAuthn/FIDO2

• Okta

• OpenID

privacyIDEA

• Base URL: please enter the URL of your privacyIDEA instance

• User name attribute: please enter the LDAP attribute name that contains the user ID (e.g. "uid")

• Optional: By default LAM will enforce to use a token and reject users that did not setup one. You can set this check to optional. But if a user has setup a token then this will always be required.

• Disable certificate check: This should be used on development instances only. It skips the certificate check when connecting to verification server.

Please note that LAM needs to authenticate to privacyIdea with the user's user name and password WITHOUT second factor. This is needed to get the list of tokens that are setup for the user. You can setup a separate policy (scope: authentication) for LAM inside privacyIdea that has IP restriction ("Client" setting) to LAM's server IP and an action "otppin" "none".

YubiKey

• Base URLs: please enter the URL(s) of your YubiKey verification server(s). If you run a custom verification API such as yubiserver then enter its URL (e.g. http://www.example.com:8000/wsapi/2.0/verify). The URL needs to end with "/wsapi/2.0/verify". For YubiKey cloud these are "https://api.yubico.com/wsapi/2.0/verify", "https://api2.yubico.com/wsapi/2.0/verify", "https://api3.yubico.com/wsapi/2.0/verify", "https://api4.yubico.com/wsapi/2.0/verify" and "https://api5.yubico.com/wsapi/2.0/verify". Enter one URL per line.

• Client id: this is only required for YubiKey cloud. You can register here: https://upgrade.yubico.com/getapikey/

• Secret key: this is only required for YubiKey cloud. You can register here: https://upgrade.yubico.com/getapikey/

• Optional: By default LAM will enforce to use a token and reject users that did not setup one. You can set this check to optional. But if a user has setup a token then this will always be required.

• Disable certificate check: This should be used on development instances only. It skips the certificate check when connecting to verification server.

Duo

This requires to register a new "Web SDK" application in your Duo admin panel.

• User name attribute: please enter the LDAP attribute name that contains the user ID (e.g. "uid").

• Base URL: please enter the API-URL of your Duo instance (e.g. api-12345.duosecurity.com).

• Client id: please enter your client id.

• Secret key: please enter your client secret.

WebAuthn/FIDO2

See the WebAuthn/FIDO2 appendix for an overview about WebAuthn/FIDO2 in LAM.

Users will be asked to register a device during login if no device is setup.

• Domain: Please enter the WebAuthn domain. This is the public domain of the web server (e.g. "example.com"). Do not include protocol or port. Browsers will reject authentication if the domain does not match the web server domain.

• Optional: By default LAM will enforce to use a 2FA device and reject users that do not setup one. You can set this check to optional. But if a user has setup a device then this will always be required.

Okta

This requires to register a new application of type "Web".

There, you will need to configure LAM's 2-factor URLs as "Login redirect URIs" in the new application. They are "https://YOURDOMAIN/lam/templates/login2Factor.php" for admin interface and "https://YOURDOMAIN/lam/templates/selfService/selfService2Factor.php?scope=user&name=YOUR_PROFILE" for self service. You will get an error message during login with the URL to configure in case it was wrong.

On "Sign On" tab you need to add a rule that prompts for the factor.

LAM options:

• User name attribute: please enter the LDAP attribute name that contains the user ID (e.g. "mail").

• Base URL: please enter the URL of your Okta domain (e.g. https://mydomain.okta.com)

• Client id: please enter your application client id.

• Secret key: please enter your application secret key.

OpenID

This will use an OpenID server as 2nd factor for authentication.

LAM options:

• User name attribute: please enter the LDAP attribute name that contains the user ID (e.g. "uid").

• Base URL: please enter the URL of your OpenID client URL. The URL is the one before the "/.well-known/openid-configuration".

• Client id: please enter your application client id.

• Secret key: please enter your application secret key.

KeyCloack example configuration:

Create a new client, select "OpenID Connect" client type and enter a client ID.

Now enable "Client authentication" and enter the valid redirect URLs in the last step.

They are "https://YOURDOMAIN/lam/templates/login2Factor.php" for admin interface and "https://YOURDOMAIN/lam/templates/selfService/selfService2Factor.php" for self service. You will get an error message during login in case it was wrong. Then save the configuration.

Next, switch to tab "Credentials" to get the client secret.

Example configuration values:

• User name: uid

• Base URL: http://openidserver/auth/realms/master

• Client id: demo

• Secret key: 59bdf504-b76e-4138-8421-ef662b2c6c83

Remember device

You can allow users to remember the 2FA device for privacyIDEA, WebAuthn and YubiKey. When a device is remembered then users can login for the specified time without presenting their 2nd factor.

The password for the device remembering is used to authenticate the device data. It can be any long passphrase (use > 30 characters). LAM auto-generates one for you. If you change the passphrase then all device data gets invalid and users need to represent their 2nd factor again (which then can be saved again).

Login

After logging in with user + password LAM will ask for the 2nd factor. If the user has setup multiple factors then he can choose one of them.

Captcha

LAM Pro can optionally display a captcha to verify that logins are not from robots. Captchas will be displayed when you tick the chekbox to secure login with a captcha. The supported captcha providers are:

Google reCAPTCHA

You will need the site and secret key for your domain. They can be retrieved from here: https://www.google.com/recaptcha

Please note that your web server must be able to access "https://www.google.com/recaptcha/api/siteverify" to verify the captchas.

Friendly Captcha

Please enter your site (see applications) and API key. The web server must be able to contact "https://api.friendlycaptcha.com" for verification.

hCaptcha

Please enter your site and secret key (not API key). The web server must be able to contact "https://hcaptcha.com" for verification.

Lamdaemon

This section is only required if you want to display file system quotas or create home directories via lamdaemon.

Server list format options:

• "server": "server" is the DNS name of your script server

• "server:NAME": NAME is the display name of this server

• "server:NAME:/prefix": /prefix is the directory prefix for all operations. E.g. creating a home directory "/home/user" would create "/prefix/home/user" then.

You need to provide a fixed user name.

Self service requires a SSH connection with SSH key. Please generate a SSH key pair and provide the location to the private key file. If the key is protected by a password you can also specify it here.

In case you want to create home directories during user self registration please provide the rights for it (e.g. 750).

Here you can specify what input fields your users can see. It is also possible to group several input fields.

Please use the arrow signs to change the order of the fields/groups.

You may also set some fields as read-only for your users. This can be done by clicking on the lock symbol. Read-only fields can be used to show your users additional data on the self service page that must not be changed by themselves (e.g. first/last name).

Sometimes, you may want to set a custom label for an input field. Click on the edit icon to set your own label text (Personal: Department is relabeled as "Business unit" here).

Possible input fields

This is a list of input fields you may add to the self service page.

This allows to configure some module specific options (e.g. custom scripts or password hash type).

LAM Pro can check the password history and minimum age for Samba 3 password changes. In this case please provide the LDAP suffix where your Samba 3 domain(s) are stored.

If you leave the field empty then no history and age checks will be done.

Password history: depending on your LDAP server you might need ascending or descending order. Just switch the setting if the password history is not correctly updated.

Schema installation

Please install the LDAP schema as described here.

Settings

You can allow your users to reset their passwords themselves. This will reduce your administrative costs for cases where users forget their passwords.

To enable this feature please activate the checkbox "Enable password self reset link".

Hint: Please note that LAM Pro uses security questions by default. Activate confirmation mails and then deactivate security questions if you want to use only email validation.

Identification method, used LDAP attributes:

You can now configure the minimum answer length for password reset answers. This is checked when you allow you users to specify their answers via the self service. Additionally, you can specify the text of the password reset link (default: "Forgot password?"). The link is displayed below the password field on the self service login page.

Next, please enter the DN and password of an LDAP entry that is allowed to reset the passwords. This entry needs write access to the attributes shadowLastChange, pwdAccountLockedTime and userPassword. It also needs read access to uid, mail, passwordSelfResetQuestion and passwordSelfResetAnswer. Please note that LAM Pro saves the password on your server file system. Therefore, it is required to protect your server against unauthorised access.

Please also specify the list of password reset questions that the user can choose.

Please note that self service and LAM admin interface are separated functionalities. You need to specify the list of possible security questions in both self service profile(s) and server profile(s).

You can inform your users via mail about their password change. The mail can include the new password by using the special wildcard "@@newPassword@@". Additionally, you may want to insert other wildcards that are replaced by the corresponding LDAP attributes. E.g. "@@uid@@" will be replaced by the user name. See here for setting up your SMTP server.

LAM Pro can send your users an email with a confirmation link to validate their email address. Of course, this should only be used if the email account is independent from the user password (e.g. at external provider) or you use the backup email address feature. The mail body must include the confirmation link by using the special wildcard "@@resetLink@@". Additionally, you may want to insert other wildcards that are replaced by the corresponding LDAP attributes. E.g. "@@uid@@" will be replaced by the user name.

There is also an option to skip the security question at all if email verification is enabled. In this case the password can be reset directly after clicking on the confirmation link. Please handle with care since anybody with access to the user's mail account can reset the password.

Captcha support

LAM Pro can optionally display a captcha to verify that password resets are not from robots. The captcha provider is configured on "General settings" tab.

Captchas will be displayed when you tick the chekbox to use a captcha.

Troubleshooting:

1. You get messages like "Unable to find user account."

This can have multiple reasons:

Turn on logging in LAM's main configuration settings. The exact reason is logged on notice level.

2. You do not see security question and answer fields when logged into self service.

Probably, the user does not have the object class "passwordSelfReset" set. You can do this in admin interface. If you have multiple users to change then use the Multi Edit Tool to add the object class.

New fields for self service page

There are special fields that you may put on the self service page for your users. These fields allow them to change the reset questions and its answers. It is also possible to set a backup email address to reset passwords with an external email address.

This is an example how can be presented to your users on the self service page:

Password reset link

After activating the password self reset feature there will be a new link on the self service login page. The text can be configured as described above (default: "Forgot password?").

When a user clicks on the link then he will be asked for identification with his user name and email address.

LAM Pro will use this information to find the correct LDAP entry of this user. It then displays the user's security questions and input fields for his new password. If the answer is correct then the new password will be set. Additionally, pwdAccountLockedTime will be removed and shadowLastChange updated to the current time if existing.

Prefilling the input fields

You might want to provide personalized URLs to your users that already prefill the fields in first step of password self reset. This can be done by adding an additional URL parameter with the attribute name in lower case.

LAM will not generate these URLs for you. This needs to be done by the system that provides the URL to your user.

Examples:

With LAM Pro your users can create their own accounts if you like. LAM Pro will display an additional link on the self service login page that allows you users to create a new account including email validation (see here for setting up your SMTP server).

You enable this feature in your self service profile. Just activate the checkbox "Enable self registration link".

Options:

Link text: This is the label for the link to the self registration. If empty "Register new account" will be used.

Admin DN and password: Please enter the LDAP DN and its password that should be used to create new users. This DN also needs to be able to do LDAP searches by uid in the self service part of your LDAP tree.

Object classes: This is a list of object classes that are used to build the new user accounts. Please enter one object class in each line. If you use LAM Pro password self reset feature then do not forget to add "passwordSelfReset" here.

Attributes: This is a list of additional attributes that the user can enter. Please note that user name, password and email address (attribute "mail") are mandatory anyway and need not be specified. Just in case you use the legacy attribute "email" for account it needs to be specified (attribute "mail" will then not be shown).

Each line represents one LDAP attribute. The settings are separated by "::". The first setting specifies the field type. The second setting is the LDAP attribute name (add ";binary" to attribute names for file upload). Depending on the field type you can enter additional options:

For a syntax description of validation expressions see here. Validation is optional, you can leave these options blank.

Examples:

Unix account:

optional::givenName::First name::/^[[:alnum:] ]+$/u::Please enter a valid first name.

required::sn::Last name::/^[[:alnum:] ]+$/u::Please enter a valid last name.

constant::homeDirectory::/home/@@uid@@

autorange::uidNumber::ou=people,dc=company,dc=com::10000::20000

If you use the object class "inetOrgPerson" and do not provide the "cn" attribute then LAM will set it to the user name value.

Active Directory/Samba4:

required::cn::Common Name::/^[[:alnum:] ]+$/u::Enter common name.

constant::userPrincipalName::@@uid@@@samba4.test

constant::sAMAccountName::@@uid@@

constant::userAccountControl::512

Please note that only simple input boxes are supported for account registration. The user may log in to self service when his account was created to manage all his attributes.

Create home directory: This will create the home directory via lamdaemon. The user must have the following attributes: uid, uidNumber, gidNumber, homeDirectory

Approval

You can send the account request to an administrator for approval. The email will include links for approval/reject. Please use the wildcards @@approveLink@@ and @@rejectLink@@ for this.

If the request was rejected then no email will be sent to the user.

Captcha support

LAM Pro can optionally display a captcha to verify that registrations are not from robots. The captcha provider is configured on "General settings" tab.

Captchas will be displayed when you tick the chekbox to use a captcha.

User view:

The user can register by clicking on a link on the self service login page:

Here he can insert the data that you specified in the self service profile:

LAM will then send him an email with a validation link that is valid for 24 hours. When he clicks on this link then the account will be created in the self service user suffix. The DN will look like this: uid=<user name>,...

This module allows you to manage LDAP attributes that are not covered by the other LAM modules (e.g. if you use custom LDAP schemas). You can fully define how your input fields look like:

To create custom fields for the Self Service please edit your Self Service profile and switch to tab "Module settings". Here you can add a new field. Simply fill the fields and press on "Add".

Please note that the field name cannot be changed later. It is the unique ID for this field.

After you created your fields please press on "Sync fields with page layout". Now you can switch to tab "Page layout" and add your new fields like any other standard field.

Examples for fields and their representation in Self Service:

Text field:

Text fields allow to specify a validation expression and error message.

You can also enable auto-completion. In this case LAM will search all accounts for the given attribute and provide auto-completion hints when the user edits this field. This should only be used if there is a limited number of different values for this attribute.

In case your field is a date value you can show a calendar for easy editing.

Example calendar formats:

You can escape wildcards with "\". E.g. "d.m.Y \d" will result in "31.12.2025 d".

Presentation in Self Service:

Password field:

You can also manage custom password fields. LAM Pro will display two fields where the user must enter the same password. You can hash the password if needed.

Presentation in Self Service:

Text area:

This adds a multi-line field. The options are similar to text fields. Additionally, you can set the size with the number of columns and rows.

Please note that the validation expression should be set to multi-line. This is done by adding "m" at the end.

Presentation in Self Service:

Checkbox:

Sometimes you may want to allow only yes/no values for your LDAP attributes. This can be represented by a checkbox. You can specify the values for checked and unchecked. The default value is set if the LDAP attribute has no value.

Presentation in Self Service:

Radio buttons:

This displays a list of radio buttons where the user can select one value.

You can specify a mapping of LDAP attribute values and their display (label) on the Self Service page. To add more mapping fields please press "Add more mapping fields".

Presentation in Self Service:

Select list:

Select lists allow the user to select a value in a large list of options. The definition of the possible values and their display is similar to radio buttons.

You can also allow multiple values.

Presentation in Self Service:

LDAP search select list

This is similar to "Select list" but the option are read from LDAP. You can use this to define e.g. a DN selection list. Multiple values are supported.

LDAP suffix: The LDAP DN that is used as starting point to search for LDAP entries.

LDAP filter: Only LDAP entries that match this filter will be used. If all entries should be used then use "(objectclass=*)".

Attribute name: The values of this attribute will be used to build the selection list.

Display attributes: List of attributes to show as label for the options in select box. Attribute wildcards are surrounded by "$", e.g. "$cn$" will be replaced by "cn" attribute. Default is "$dn$".

Presentation:

LDAP date

Use this for LDAP attributes with syntax "Generalized Time" (1.3.6.1.4.1.1466.115.121.1.24).

LAM will automatically set hour/minute/second to "0". If this is not intended please use type "LDAP date and time".

Presentation:

LAM will display a calendar to select the date.

LDAP date and time

Use this for LDAP attributes with syntax "Generalized Time" (1.3.6.1.4.1.1466.115.121.1.24).

LAM can convert the displayed value to the configured time zone of your server/self service profile. In this case, please activate "Display in local time".

Presentation:

LAM will display a calendar to select the date and time.

Constant value

This will set the attribute to a constant value. You can also specify wildcards to inject other attribute's values.

Wildcards:

Examples for attributes gn="Steve", sn="Miller" and memberUid=("user1", "user2") (specified value -> resulting LDAP value):

Presentation:

The LDAP value will be shown as text.

File upload:

This is used for binary data. You can restrict uploaded data to a given file extension and set the maximum file size.

Presentation:

The uploaded data may also be downloaded via LAM.

Validation expressions:

The validation expressions follow the standard of Perl regular expressions. They start and end with a "/". The beginning of a line is specified by "^" and the end by "$".

Examples:

/^[a-z0-9]+$/ allows small letters and numbers. The value must not be empty ("+").

/^[a-z0-9]+$/i allows small and capital letters ("i" at the end means ignore case) and numbers. The value must not be empty ("+").

Special characters that must be escaped with "\": "\", ".", "(", ")"

E.g. /^[a-z0-9\.]$/i

This allows your users to setup OpenLDAP TOTP tokens.

Please note that this requires to use a bind user that is also used for all operations. This user needs to be able to add/remove the TOTP object classes and attributes.

On page layout tab you can then add the fields for serial number (optional) and the token. Users will then be able to manage their token via self service.
