s4:dsdb/rootdse: Support netlogon request
This patch adds support for a netlogon ldap style request over the tcp socket. This is available since win2k3+ [1]. The automatic client join & configuration daemon "realmd" makes use of this ability. Realmd can now be used to join a computer to a samba 4 domain. (See also: https://lists.samba.org/archive/samba-technical/2013-October/095606.html) Tested with: ldapsearch -h samba-srv -x -b '' -s base "(&(NtVer=\06\00\00\00)(AAC=\00\00\00\00))" NetLogon And compared the result in wireshark with cldap request issued by examples/misc/cldap.pl.
