GLPI Groups LDAP Intergration

I'm using LDAP authentication with no problems for user accounts in GLPI. But now I'm trying to get GLPI Groups to link to my LDAP groups. I can do the 'import' fine however the groups do not have any users in them. I used the settings from here:

GLPI-Wiki/wiki/doku.php?id=en:ldap directory

My settings are:

Search Type : In Users
User Attributes containing groups : memberof
Filter to search in groups : (objectClass=*)
Group Attributes Containing Users : <Blank>

Has anyone got this working?

Turns out that it was working just fine. In order for the group membership for a user in a group to update, the user has to login to GLPI. :)
