Just for completion, this was the first reply to my problem who pointed me into the direction of sssvlv and valsort.

Hi Benjamin,
It looks like your LDAP client is asking the server to return ordered results from looking at this line:
tag=101 err=18 nentries=0 text=serverSort control: No ordering rule
You may want to take a look at the server-side sorting overlay (slapo-sssvlv) and/or the value sorting overlay (slapo-valsort) and see if activating them on the server will fix your problems.
