yourls-ldap-plugin

This plugin for YOURLS enables the simple use of LDAP for user authentication.

Installation

1. Download the latest yourls-ldap-plugin.
2. Copy the plugin folder into your user/plugins folder for YOURLS.
3. Set up the parameters for yourls-ldap-plugin in YOURLS configuration user/config.php (see below).
4. Activate the plugin with the plugin manager in the admin interface.

Usage

When yourls-cas-plugin is enabled and user was not successfuly authenticated using data specified in yourls_user_passwords, an LDAP authentication attempt will be made. If LDAP authentication is successful, then you will immediately go to the admin interface.

You can also set a privileged account to search the LDAP directory with. This is useful for directories that don't allow anonymous binding.

Setting the groups settings will check the user is a member of that group before logging them in and storing their credentials. This check is only performed the first time they auth or when their password changes.

Configuration

• define( 'LDAPAUTH_HOST', 'ldaps://ldap.domain.com' ) LDAP host name, IP or URL. You can use ldaps://host for LDAP with TLS
• define( 'LDAPAUTH_PORT', '636' ) LDAP server port - often 389 or 636 for TLS (LDAPS)
• define( 'LDAPAUTH_BASE', 'dc=domain,dc=com' ) Base DN (location of users)
• define( 'LDAPAUTH_USERNAME_FIELD', 'uid') (optional) LDAP field name in which username is store

To use a privileged account for the user search:

• define( 'LDAPAUTH_SEARCH_USER', 'cn=your-user,dc=domain,dc=com' ) // (optional) Privileged user to search with
• define( 'LDAPAUTH_SEARCH_PASS', 'the-pass') // (optional) (only if LDAPAUTH_SEARCH_USER set) Privileged user pass

To check group membership before authenticating:

• define( 'LDAPAUTH_GROUP_ATTR', 'memberof' ) // (optional) LDAP groups attr
• define( 'LDAPAUTH_GROUP_REQ', 'the-group') // (only if LDAPAUTH_GROUP_REQ set) Group user must be in

Troubleshooting

• Check PHP error log usually at /var/log/php.log
• Check your webserver logs
• You can try modifying plugin code to print some more debug info
