Use LDAP Groups as ACL Group Aliases in WackoWiki

With this hack, your Wacko Wiki? gets an ACL Group Alias for every groupOfName Object. So you can reuse your LDAP Groups in your Wiki.

1. Put the file ldapgroups.php in your classes dir
2. Customize it for your environment (LDAP connection parameters, DIT location of your Groups, eregi_replace lines to generate the User Wiki Names?)
3. Create a file actions/ldapgroups.php with this content:


<?php
  global $wakkaConfig;
  show_array($wakkaConfig["aliases"]);
?>

4. Add this lines at end the of your wakka.config.php:

# Changes for ldap-groups include("classes/ldapgroups.php"); $wakkaConfig["aliases"] = add_ldap_groups_to_array($wakkaConfig["aliases"]);
Now you can create an admin page with the action {{ldapgroups}} to display all possible ACL Group aliases.

Good luck :-)
