[Users] ovirt 3.4.0-0.5.beta1 and OpenLDAP groups

Hi All, I managed to use OpenLDAP to integrate with oVirt 3.4.0-0.5.beta1. For this, I followed (more or less, I used a Raspberry Pi and Raspbian) instructions as found on http://www.ovirt.org/LDAP_Quick_Start It all seems to work well, I am able to connect to a domain, login etc. and assign some roles to users. However, I cannot use (ldap) groups it seems. I cann add a group in the ovirt gui, but (in the tab General) "Active" remain "false". A I missing something...? Winfried
