OpenGroupware and Kolab

[Henning Burow]

Hi,

is there anybody running OpenGroupware and Kolab? My users will use 
OpenGroupware for timemangement, ... and i want to use Kolab below that, to 
provide the mail server with spam and virus detection. As Kolab uses openldap 
for user management, and opengroupware can connect to an openldap server to 
get the users and passphrases, i would have to insert and remove users just 
once. Can someone give me some insights on that combination? Especially on 
the ldap connection settings, leading to the users and there passphrases. 

Thanks,
Henning
