Maybe there's a misunderstanding here, but Novell's jldap library does
work fine. It's the use of the javax.naming.ldap classes that does
not.

Actually, I've done some more digging regarding that problem and it
seems that it's related to the Fuse OSGi Container that I'm using.
I've posted my findings there:
