======== FINISH ======

I expected to see uid=SH0180,ou=contacts,ou=china,dc=ahk,dc=de in the search result in step 2 but couldn't. Similiar problem happen on commonName as well, on both of our two installations, one is running 2.4.9 and the other 2.3.30. Both using hdb.

It is totally confusing to me that I don't even know where to start look for the problem. Should I also attach full slapd.conf?

Thanks for any input in advance. I am totally clueless now, even after running the installation for 3 years it's the first time see such frastrating situation. Thanks.
