Try to catch up on the code I've put into HEAD that should be in 3.0:

 - vorlan's hosts allow with DNS names patch
 - use x_fileno() in debug.c, not the struct directly.
 - check for server timeout on password change (was reporting success)
 - better error/status loggin in both the pam_winbind client and winbindd_pam
server code.
 - (pdb_ldap) don't set the ldap version twice - we do it on every bind anyway.
(This used to be commit 9fa1863d8e7788eda83911ca2610754486b33069)
