[Samba] Problem with samba 2.2.3a configured to use domain security

[Chandler, Todd]

I am having a problem with getting samba 2.2.3a to work with our current set
up.  I used to have samba 2.0.7 working perfectly, but decided to upgrade to
try and get Win2k clients to be able to access the shares on the UNIX system
hosting samba.

When I try and access any of the shares on samba (it doesn't matter who the
client is) I get the following messages produced in the log file:

[2002/03/13 10:35:14, 0] rpc_client/cli_netlogon.c:cli_net_auth2(157)
  cli_net_auth2: Error NT_STATUS_ACCESS_DENIED
[2002/03/13 10:35:14, 0] rpc_client/cli_login.c:cli_nt_setup_creds(74)
  cli_nt_setup_creds:auth2 challenge failed
[2002/03/13 10:35:14, 0] smbd/password.c:
connect_to_domain_password_server(1335)
  connect_to_domain_password_server: unable to setup the PDC crenditial to
machine X. Error was NT_STATUS_OK.
[2002/03/13 10:35:14, 0] smbd/password.c: domain_client_validate (1554)
  domain_client_validate: Domain password server not available.

Apparantly something has gone wrong between the PDC and samba.  I have
removed the UNIX machine from the domain and re-added it back per the
instructions that come with the samba distribution.

I compiled the binaries myself with the default options.  

What changed from 2.07 to 2.2.3a to kill the security=domain setting from
working?  Is there some configuration switch that I should have turned on
when compiling the binaries?  Is this a bug or a stupid user configuration
problem?
