I am having a problem with Ldap Auth/Squid. certain restricted users being prompted multiple times for auth even though it should be cached. This behaviour happens with a site such as http://www.euroinvestor.co.uk/ many others as well. This also did not happen in squid2.5.6 but happens constantly in squid2.6.14 or squid2.6.16, i am guessing its some ldap config setting but who knows. Config info etc: Squid Cache: Version 2.6.STABLE16 configure options: '--prefix=/usr/local/squid2.6.16' '--enable-basic-auth-helpers=LDAP' '--enable-external-acl-helpers=ldap_group' '--enable-storeio=aufs,ufs entries in squid.conf: auth_param basic program /usr/local/squid2.6.16/libexec/squid_ldap_auth -d -P -b o=businesswire.com -h servername.businesswire.com -f (uid=%s) auth_param basic children 15 auth_param basic realm Business Wire Internet logon - Use InsideTrak username and password to log on auth_param basic credentialsttl 1 minute auth_param basic casesensitive off external_acl_type sfapp2ldapgroup %LOGIN /usr/local/squid2.6.16/libexec/squid_ldap_group -d -b "cn=Organization,cn=Businessw ire Employees,o=businesswire.com" -f (&(cn=%a)(uniquemember=uid=%v*)) -h sfapp2.businesswire.com Or maybe it's an ACL thing but cant figure out why it worked in squid2.5.6 but not in 2.6.16 with the same squid.conf config paramters. Thanks
