samba - Oct 2003 - ntlm_auth does not work with win98

Hello,

I am using ntlm_auth from samba-3.0.0 with squid 2.5.STABLE3.
Win2k clients can authenticate, but win98 not.

In squid cache.log I see:

libsmb/ntlmssp.c:ntlmssp_server_auth(278)
  ntlmssp_server_auth: failed to parse NTLMSSP:

My squid.conf has:

auth_param ntlm program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp
auth_param ntlm children 2
auth_param ntlm max_challenge_reuses 0
auth_param ntlm max_challenge_lifetime 2 minutes

acl AuthorizedUsers proxy_auth REQUIRED
http_access allow AuthorizedUsers

Regards,
Nerijus
