Samba/SWAT 2.0.4b (running on SunOS 4.1.x, SunOS 5.7 and Red Hat 5.2) fails to authenticate when using Squid/2.1.PATCH2. The failure manifests itself immediatly (ie. before the username/password dialogue). [This is not my proxy so I havent yet had the opportunity to examine the logs]. The same Samba/SWAT 2.0.4b servers have no authentication problems with other proxies (including CERN 3.0A!!!) and all our and other password protected pages authenticate correctly with Squid/2.1.PATCH2. I assume this might be a Squid problem but cannot see any Squid or Samba messages which mention similar problems. Anyone else running Squid/2.1.PATCH2 and SWAT without problems? Andrew
