Some more info:

After adding a group to a "nag" share, nag dies on startup.

/datastore/share/pear/www/horde/nag/task.php:81
2. Horde_Group_Intranator->listUsers()

-> One can see that it tries to call  
"Horde_Group_Intranator->listUsers()" with the group name instead of  
the group id. I've digged a bit around the code and can see that the  
Kolab $share returns the group name instead of a group id.

For now I've traced it to Horde/Share/Object.php::listGroups() calling  
$perm->getGroupPermissions(). This somewhere ends up in  
Horde/Perms/Permission/Kolab/Acl/Group.php.  Adding a debug trace to  
::toHorde() shows "$this->_id" is the group name.

-> The custom "Intranator" group driver uses an integer id as group id  
while the Kolab backend expects the "group name" as id. I'll fix my  
custom group driver since the Kolab backend does not have any "id"  
information available from the "group:NAME" acls on the IMAP server.
