commit 3b73cdb41201dd545e019e8e8313f6b8c51c7226
Author: Stefan Metzmacher <me...@samba.org>
Date: Wed Jan 28 10:10:12 2009 +0100
s3:nmbd: implement a MAILSLOT => CLDAP proxy for NETLOGON_SAMLOGON requests
This will be used as part a the franky setup, where nmbd will forward
the MAILSLOT requests to the local samba4 CLDAP server.
"nmbd_proxy_logon:cldap_server = 127.0.0.1" would configure
and activate this feature.
