I would like to know whether netlogon queries over TCP are currently
possible with samba 4?
According to the wireshark wiki that is supported as of win 2k3 server.
The automatic client join&configuration daemon realmd makes use of that
(it checks whether the server reports win2k3+) and currently returns:
! Received invalid or unsupported Netlogon data from server
I tried to reproduce realmd's beaviour with ldapsearch:
ldapsearch -h dc -x -b '' -s base
This returns zero results when "dc" is a samba 4 server. (Thats why the
But with a windows 2k8 server I got a netlogon result:
I found no tcp initialization in the cldap server code, or any hooks in
ldap_server that call into cldap_request. Am i overseeing something?
(I'm asking since metze said on irc: 13:55 < metze> bnf: samba4 should also
support it over tcp)
Is it planned to add this to samba or should realmd be fixed to always use
udp for cldap-style netlogon queries? (though i guess, since AD does this,
samba more or less has to support it..)
