In some cases, the chain overlay uses an automatic ldapinfo structure, which is
a copy of the original one except for the url.  This results in (at least)
leaking connections in the connection tree; it may also result in a corrupted
AVL tree and even worse, because mutex locking occurs on copies of the mutexes
and so.
