[horde] Group rights for calendar

[steffo76 at gmx.de]

Hello there,

I have a question regarding group rights in kronolith. My horde4 installation knows groups via ldap and I can see all groups via Administration->Groups. 

I would like for each group to have its own calendar which is only accessible for members of that group. I created the first of these calendars and made it a system calendar. Clicking the key symbol I would like to edit the permissions but the only group showing up in the group dropdown box is the one I am a member of. I have administrative rights and can see the groups in the Administration section. How do I persuade kronolith to show me all groups available ?

Regards
Stephan
