[squid-users] NTLM problems during higher loads

Hi,
 
During the peak hours I constantly got problems with NTLM
authentication. The cache.log contains the "ntlmssp_server_auth:
failed to parse NTLMSSP" line, and some clients ramdonly asked for
password.
 
I tried to update to samba-3.0.14a (I was using the Fedora Core 3
version 3-0.10-1-fc3), and it seems that these message disappeared,
but another one popped up:
 libsmb/ntlmssp.c:ntlmssp_update(252)
  got NTLMSSP command 3, expected 1
 
Is this harmless?
 
(Squid version 2.5Stable9, from Fedora Core 3 RPM)
