Hi!

Trying to start test server (openldap 2.4.25) on my home box (FreeBSD 
8.2 i386) I get this error:

...

I'm new to openldap software, so I have no guess what's the reason 
behind the error. I googled that error 68 means that there is duplicate 
entry in the DIT but there is no text part in the message so I don't 
know what entry is causing the error.

Any help would be greatly appreciated!
