[horde] errors in using LDAP groups

[kenren taisho]

Hi List,

Anyone successfully using LDAP groups and can give me a hand?
Although under group menu, I am getting group listings and the members are
successfully enumerated, still I don't have group functionality in
applications like calendar.
I am getting a lot of these errors:

"Bad search filter Parameters: Base: ou=groups,dc=xx,dc=xxxxx,dc=xxx Filter:
(&(objectclass=)(=my.uid)) Scope: sub"
"PHP ERROR: Undefined index: objectclass [pid 5650 on line 286 of
"/usr/share/pear/Horde/Ldap/Filter.php"
"PHP ERROR: Undefined index: uid [pid 5650 on line 863 of
"/usr/share/pear/Horde/Ldap.php"

Just opening the calendar will result in those errors, there is also no
group sharing available for the calendar and tasks.

Here is my  conf.php, I am using the webmail edition version 4.0.2.

Any help is greatly appreciated.


thanks and best regards
