NT PDC authentication problems

[Tom Kostin]

Hi !
I have very strange problem with SAMBA  2.0.7 ( platform Linux 2.2.14 ) .
The smb.conf file : 
[global]
   workgroup = envelopes
   netbios name = saturn 
   server string = File Server

   
   log file = /var/log/samba/log.%m
   max log size = 5000

   max open files =  1010 # this was added because of SAMBA complains about
concurrent open files . 


   log level = 1

   security = domain
   password server = *
   encrypt passwords = yes
   smb passwd file = /etc/smbpasswd
   username map = /etc/smbusers


I have joined domain and everything worked fine until I encountered strange
problem :
There are some random users that sometimes can't be authenticated by PDC and
BDC  and access shares on SAMBA server as user 'nobody'. It's almost random
event , one time user connects as user on machine  and second time he
connects as 'nobody' .

I've tried to use ' password server = PDC BDC '  -  nothing changed . 

Any suggestions ? 

Tom .
