Hi list, I am investigating a problem with squid and Exchange at the moment. We are using a self-compiled squid-3.0.stable15 and people can not use Exchange OMA/OWA through the squid proxy. It does not display a login prompt, the page that is returned by Exchange shows a "HTTP Error 401.2". Using a squid-2.7.stable5 rpm from a SLES11 server does not show this behavior. The OMA/OWA is accessible through the proxy. -- Squid Cache: Version 2.7.STABLE5 configure options: '--prefix=/usr' '--sysconfdir=/etc/squid' '--bindir=/usr/sbin' '--sbindir=/usr/sbin' '--localstatedir=/var' '--libexecdir=/usr/sbin' '--datadir=/usr/share/squid' '--mandir=/usr/share/man' '--with-dl' '--with-maxfd=4096' '--with-valgrind-debug' '--enable-snmp' '--enable-carp' '--enable-auth=basic digest negotiate ntlm' '--enable-basic-auth-helpers=LDAP MSNT NCSA PAM SMB YP getpwnam multi-domain-NTLM' '--enable-ntlm-auth-helpers=SMB fakeauth no_check' '--enable-digest-auth-helpers=ldap password' '--enable-external-acl-helpers=ip_user ldap_group session unix_group wbinfo_group' '--enable-ntlm-fail-open' '--enable-arp-acl' '--enable-htcp' '--enable-underscores' '--enable-stacktraces' '--enable-delay-pools' '--enable-useragent-log' '--enable-referer-log' '--enable-forward-log' '--enable-multicast-miss' '--enable-ssl' '--enable-cache-digests' '--enable-auth-on-acceleration' '--enable-storeio=aufs,coss,diskd,null,ufs' '--enable-linux-netfilter' '--enable-removal-policies=heap,lru' '--enable-icmp' '--with-samba-sources=/usr/include/samba' '--enable-large-cache-files' '--enable-x-accelerator-vary' '--enable-follow-x-forwarded-for' 'CFLAGS=-march=i586 -mtune=i686 -fmessage-length=0 -O2 -Wall -D_FORTIFY_SOURCE=2 -fstack-protector -funwind-tables -fasynchronous-unwind-tables -g -fPIE -DLDAP_DEPRECATED -fno-strict-aliasing' 'LDFLAGS=-pie' -- Using a self-compiled squid-2.7 on Solaris 10 with the following options, works as well (login to Exchange is ok). -- configure options: '--enable-icap-client' '--enable-ssl' '--prefix=/apps/squid-3' '--enable-storeio=aufs' '--with-aio-threads=N' '--enable-removal-policies' '--enable-snmp' '--enable-icmp' '--enable-htcp' '--enable-cache-digests' -- Using a squid-3.1 (3.1.0.15) on Solaris10 with the same options as above works (login to Exchange is ok). -- configure options: '--enable-icap-client' '--enable-ssl' '--prefix=/apps/squid-3' '--enable-storeio=aufs' '--with-aio-threads=N' '--enable-removal-policies' '--enable-snmp' '--enable-icmp' '--enable-htcp' '--enable-cache-digests' -- But using a squid-3.0.stable15/stable20 on Solaris10, same options - the Exchange server returns a "HTTP Error 401.2" -- configure options: '--enable-icap-client' '--enable-ssl' '--prefix=/apps/squid-3' '--enable-storeio=aufs' '--with-aio-threads=N' '--enable-removal-policies' '--enable-snmp' '--enable-icmp' '--enable-htcp' '--enable-cache-digests' -- Is this a problem with connection pinning (http://wiki.squid-cache.org/Features/ConnPin), that has been re-implemented in 3.1?
