[Samba] Error: _netr_ServerAuthenticate2: netlogon_creds_server_check failed.

[Christopher Springer]

  My configuration is a multi-subnet, multi-subnet Samba/OpenLDAP 
configuration.  Everything works fine on both subnets but I'm getting 
the following error in /var/log/messages and in /var/log/samba/log.smbd...

_netr_ServerAuthenticate2: netlogon_creds_server_check failed. Rejecting 
auth request from client XXX30874 machine account XXX30874$

This messages seems to be repeated every time someone logs into their 
machine or when the machine has to contact the server for authentication 
purposes.  I have not had a chance to go through all of the logs and 
verify what OS's are the offenders but it appears that a lot of them are 
old WindowsNT4 machines.

Please note that the only server on the subnet in question is the BDC.  
It has a local, replicated LDAP directory against which logins are 
authenticated.  nmbd/wins is used for host name/netbios visibility.

Any ideas to getting rid of this error in the log file?  Again, it 
appears that access to files is working fine...it's just an annoyance 
because I don't understand why it's happening.

Thanks.

Chris
