- * Authenticate a user against an LDAP directory

- *
- * Optionally authenticates only if a member of a given group in the directory.
- *
- * The person must have registered with Friendika using the normal registration
- * procedures in order to have a Friendika user record, contact, and profile.
- *
- * 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 required configuration options for this module may be set in the .htconfig.php file
- * e.g.:
- *
- * $a->config['ldapauth']['ldap_server'] = 'host.example.com';
- * ...etc.
