[Samba] Server signing bugs with CIFS VFS client

[Josh Kelley]

Since upgrading to Samba 3.0.23a, mounting a Samba share using
mount.cifs generates the following errors in the Samba server's logs:

Aug  7 17:45:08 pccentos4 smbd[5345]: [2006/08/07 17:45:08, 0]
libsmb/smb_signing.c:srv_check_incoming_message(720)

Aug  7 17:45:08 pccentos4 smbd[5345]: [2006/08/07 17:45:08, 0]

Aug  7 17:45:08 pccentos4 smbd[5345]:   srv_check_incoming_message:
BAD SIG: seq 2 got SMB signature of

The errors appear to be harmless.  I get similar errors even after
applying the patch from
https://bugzilla.samba.org/show_bug.cgi?id=4003 or trying
SAMBA_3_0_RELEASE.

(I was also getting "permission denied" errors using CIFS VFS to
access a Samba 3.0.23a server, but those appear to be fixed in
SAMBA_3_0_RELEASE.)
