[Samba] Safe to ignore this message ? -Attempt to bind using schannel without successful serverauth2

[Paul S]

OS:  SLES 9
Samba Version:  3.0.20b-3.4-SUSE
Server is running in test mode, as a PDC

I find this message in my log files quite frequently, the majority coming
from one particluar machine (XP SP2):

[2006/05/19 10:35:06, 0] rpc_server/srv_pipe.c:api_pipe_bind_req(981)
  Attempt to bind using schannel without successful serverauth2
[2006/05/19 10:40:16, 0] rpc_server/srv_pipe.c:api_pipe_bind_req(981)
  Attempt to bind using schannel without successful serverauth2

The server seems to function properly so far, thus I am wondering if I can
safely ignore this message.

Workstations are able to join the domain and log in.  File sharing seems to
work well.  The speed and responsiveness of network browsing  is quite
impressive.  I have no complaints about functionality.

While researching this message, I found a post on the lists archives (Sun

that this message is part of normal operation.

If anyone can confirm that this is part of normal operation, or shed some
light on what this means, I would appreciate it.  We have been using Samba
2.2.8a for a few years now, and entries to the log files are very
infrequent.  Perhaps the newer versions are just more chatty to the log
files.

If there is something wrong, I would like to deal with it before I go live
with the server.

Below is my smb.conf file, minus the shares.
