Re: changing the dn; various breakage.

[Mark W. <mew...@un...>]

You can't use a standard modify to just change the DN of the entry. You
must do a modrdn (can't remember if that's in the current api or not,
check the docs).

If you want to use modify to change the dn of an entry, you must copy all
of the attributes from the old entry into an Entry object, set the new dn
and then add that object to the server.
