[Samba] Problem with joining WindowsXP to samba domain after upgrade from samba 3.5.11 to 3.6.1

[Ireneusz Piasecki]

Hi all.

I had samba domain in version 3.5.11. Then i made upgrade to version 
3.6.1. I use samba from Sernet on my centos 5.7 machine x86_64. After 
upgrade i restarted samba.

Since then in my log i have reapeating message:

Nov 10 09:27:59 165G6 smbd[25702]: [2011/11/10 09:27:59.246183,  0] 
rpc_server/netlogon/srv_netlog_nt.c:976(_netr_ServerAuthenticate3)

Since then i can not join any machine with Windows XP to my domain. I 
see this in log of this machine:

[2011/11/09 15:38:45.434190,  0] 
passdb/pdb_tdb.c:810(tdb_update_ridrec_only)
   Unable to modify TDB passwd: NT_STATUS_UNSUCCESSFUL!

What is going on ? I will probably revert back to samba 3.5 line (3.5.12).
