Description Liban Hannan 2014-04-27 23:31:29 UTC 
When trying to join an Samba AD domain with realmd I get the following error:

! Received invalid or unsupported Netlogon data from server


After finding the following email -
https://lists.samba.org/archive/samba-technical/2013-October/095606.html

It seems that Samba does not respond to netlogon queries over tcp, whereas Microsoft AD does (on Windows Server 2003 and later).

This can be verified using the following command -

ldapsearch -h dc1.samdom.example.com -x -b '' -s base "(&(NtVer=\06\00\00\00)(AAC=\00\00\00\00))" NetLogon

This returns no results -

# extended LDIF
#
# LDAPv3
# base <> with scope baseObject
# filter: (&(NtVer=\06\00\00\00)(AAC=\00\00\00\00))
# requesting: NetLogon
