Beside that, it's a duplicate of bug 378 and bug 764. I agree with 
Chuck that this solution is questionable, you should discuss this on 
the mailing list with other LDAP experienced users, and add to ticket 
764 if you still think that needs to be fixed.

My understanding, somewhat second hand, is that this is *not* 
necessarily a good thing to do for LDAP, and not really supported by 
the spec and standards. Do you have evidence/knowledge to the contrary?

This patch converts also the DN string into character set:
