Subject: working on transtive trusts issue:

  * use DsEnumerateDomainTrusts() instead of LDAP search.
    wbinfo -m now lists all trusted downlevel domains and
    all domains in the forest.

Thnigs to do:

  o Look at Krb5 connection trusted domains
  o make sure to initial the trusted domain cache as soon
    as possible
(This used to be commit 0ab00ccaedf204b39c86a9e1c2fcac5f15d0e033)
