[horde] groups not available

[bastian-horde-ml2015 at t6l.de]

Hello all,

A quick question:

I use 5.3.0-git with a LDAP backend for authzn.
For the administrator all groups from the LDAP are visible (e.g. for
sharing the calendars) but for non-administrators the list of groups is
empty when sharing calendars.

Access to LDAP works fine and I can see successfull searches on the
slapd side. Any hints?

Cheers,
