RE: [squid-users] Authentication Issue with Squid and mixed BASIC/NTLM auth

Hmmm, strange. I tested 2.7STABLE4, but it doesn't seem to be stripping
the DOMAIN, it will still accept only DOMAIN\USERNAME. Perhaps I'm
missing something?

I also tested squid-3.1-20081016, built with a spec file adopted from a
squid3.0STABLE7 Redhat package:

configure \
   --exec_prefix=/usr \
   --bindir=%{_sbindir} \
   --libexecdir=%{_libdir}/squid \
   --localstatedir=/var \
   --datadir=%{_datadir} \
   --sysconfdir=/etc/squid \
   --disable-dependency-tracking \
   --enable-arp-acl \
   --enable-auth="basic,digest,ntlm,negotiate" \
 
--enable-basic-auth-helpers="LDAP,MSNT,NCSA,PAM,SMB,YP,getpwnam,multi-do
main-NTLM,SASL" \
   --enable-cache-digests \
   --enable-cachemgr-hostname=localhost \
   --enable-delay-pools \
   --enable-digest-auth-helpers="password" \
   --enable-epoll \
 
--enable-external-acl-helpers="ip_user,ldap_group,unix_group,wbinfo_grou
p" \
   --enable-icap-client \
   --enable-ident-lookups \
   --enable-linux-netfilter \
   --enable-ntlm-auth-helpers="SMB,fakeauth" \
   --enable-referer-log \
   --enable-removal-policies="heap,lru" \
   --enable-snmp \
   --enable-ssl \
   --enable-storeio="aufs,coss,diskd,,ufs" \
   --enable-useragent-log \
   --enable-wccpv2 \
   --with-default-user="squid" \
   --with-filedescriptors=16384 \
   --with-dl \
   --with-openssl=/usr/kerberos \
   --with-pthreads

And it looks like NTLM could be broken (I don't want to make
assumptions). I was unable to pass credentials in either the
DOMAIN\USERNAME or USERNAME format to OWA through squid. It also forced
an NTLM prompt for Firefox that I had to escape out of before I could
authenticate with BASIC auth.

I wasn't able to test spell-check as I couldn't authenticate to the OWA
server.

Thanks!

Ah, now that you mention it I vaguely recall the topic as it flew past a

while back.

Yes, 2.7 is likely the most dependable to have both combos of fixes you
need.

Without knowing the cause the spellcheck issue _may_ have been resolved
in 3.1. Both of the MS workarounds and 'unknown method' support are now

present. If you have a spare moment and are inclined to test it please
let us know the result. If you still hit bad news for 3.1, its
definitely a bug that needs looking into at some point.
