I have Squid-2.5STABLE3 setup with Samba 2.2.8a and basic and NTLM via the winbind and wb_group helpers. Everything runs perfectly.
On this box I also installed squid-3.0-PRE3-20030820 to test the new Squid-3 series using the same auth setup as my 2.5STABLE3 install. There are a few issues: 1) I sometimes get prompted for the username and password. Right now I am the only one using this copy of Squid, and it's launching 10 NTLM helpers. 2) I'm getting several of these errors in cache.log, after which Squid restarts itself: 2003/08/20 13:41:37| assertion failed: ntlm/auth_ntlm.cc:962: "authenticateReque stRefCount(conn->auth_user_request) == 1" None of this occured with the 2.5STABLE3 install. I saw nothing in the list archives or Bugzilla regarding these problems. The box is RedHat 7.3 running a custom 2.4.18-24 kernel. #./squid -v Squid Cache: Version 3.0-PRE3-20030820 configure options: '--prefix=/opt/squid3' '--enable-storeio=aufs' '--enable-delay-pools' '--enable-err-language=English' '--enable-auth=basic,ntlm' '--enable-basic-auth-helpers=winbind' '--enable-ntlm-auth-helpers=winbind' '--enable-ntlm-fail-open' '--enable-external-acl-helpers=winbind_group' '--disable-wccp' '--enable-removal-policies=heap' '--disable-ident-lookups' '--disable-carp'
