[horde] Cannot add single users to view my kronolith calendar

Hmm. The Server allows anonymous binds. And also allowed before.

If I eg. run the command

ldapsearch -LLL uid=* 

I get a list of all accounts.

I again checked the logs of my ldap-server.
When I open the permissions of my calendar and give a username to allow the 
access. I get the beloved "User xyz does not exist" and in the logs of server 
following entries belonging to this action:

Sep 14 10:10:15 mainsrv1 slapd[4999]: conn=8250 fd=105 ACCEPT from 
IP=192.168.16.137:37572 (IP=0.0.0.0:389)
Sep 14 10:10:15 mainsrv1 slapd[4999]: conn=8250 op=0 BIND dn="" method=128
Sep 14 10:10:15 mainsrv1 slapd[4999]: conn=8250 op=0 RESULT tag=97 err=0 text=
Sep 14 10:10:15 mainsrv1 slapd[4999]: conn=8250 op=1 SRCH base="dc=iup,dc=uni-
bremen,dc=de" scope=2 deref=0 filter="(&(objectClass=posixAccount))"
Sep 14 10:10:15 mainsrv1 slapd[4999]: conn=8250 op=1 SRCH attr=uid
Sep 14 10:10:15 mainsrv1 slapd[4999]: conn=8250 op=1 SEARCH RESULT tag=101 
err=4 nentries=0 text=
Sep 14 10:10:15 mainsrv1 slapd[4999]: conn=8250 op=2 UNBIND
Sep 14 10:10:15 mainsrv1 slapd[4999]: conn=8250 fd=105 closed

err=4          means LDAP_SIZELIMIT_EXCEEDED
Which can't really be. Also larger searches work properly and the sizelimit is 
set relatively high. 

I googled a little bit and often it's said that the err=4 belongs to the 
client side.

But also the horde-log doesn't show me any interesting messages belonging to 
the ldap.
Only the "_username_hook_tobackend in application horde not called" looks 
strange. This happens twice and I also see two of the above entries in the 
ldap-logs.

See in the attached message-block the time where I tried to add a single user.

Any suggestions ?

Thanks 

Heiko
