/**
|
|
* Friendica addon
|
|
*
|
|
* Module: LDAP Authenticate
|
|
*
|
|
* Authenticate a user against an LDAP directory
|
|
* Useful for Windows Active Directory and other LDAP-based organisations
|
|
* to maintain a single password across the organisation.
|
|
*
|
|
* Optionally authenticates only if a member of a given group in the directory.
|
|
*
|
|
* By default, the person must have registered with Friendica using the normal registration
|
|
* procedures in order to have a Friendica user record, contact, and profile.
|
|
* However, it's possible with an option to automate the creation of a Friendica basic account.
|
|
*
|
|
* Note when using with Windows Active Directory: you may need to set TLS_CACERT in your site
|
|
* ldap.conf file to the signing cert for your LDAP server.
|
|
*
|
|
* The configuration options for this module may be set in the .htconfig.php file
|
|
* e.g.:
|
|
*
|
|
* // ldap hostname server - required
|
|
* $a->config['ldapauth']['ldap_server'] = 'host.example.com';
|
|
* // dn to search users - required
|
|
* $a->config['ldapauth']['ldap_searchdn'] = 'ou=users,dc=example,dc=com';
|
|
* // attribute to find username - required
|
|
* $a->config['ldapauth']['ldap_userattr'] = 'uid';
|
|
*
|
|
* // admin dn - optional - only if ldap server dont have anonymous access
|
|
* $a->config['ldapauth']['ldap_binddn'] = 'cn=admin,dc=example,dc=com';
|
|
* // admin password - optional - only if ldap server dont have anonymous access
|
|
* $a->config['ldapauth']['ldap_bindpw'] = 'password';
|
|
*
|
|
* // for create Friendica account if user exist in ldap
|
|
* // required an email and a simple (beautiful) nickname on user ldap object
|
|
* // active account creation - optional - default none
|
|
* $a->config['ldapauth']['ldap_autocreateaccount'] = 'true';
|
|
* // attribute to get email - optional - default : 'mail'
|
|
* $a->config['ldapauth']['ldap_autocreateaccount_emailattribute'] = 'mail';
|
|
* // attribute to get nickname - optional - default : 'givenName'
|
|
* $a->config['ldapauth']['ldap_autocreateaccount_nameattribute'] = 'cn';
|
|
*
|
|
* ...etc.
