Hello, I'm trying to get Squid 2.6.STABLE13 from FC6 to authenticate against a Windows 2003 Active Directory Domain but I'm getting the following error squid_ldap_auth: WARNING, could not bind to binddn 'Can't contact LDAP server' I'm using the following in the squid.conf (edited to remove site info) : auth_param basic program /usr/lib/squid/squid_ldap_auth -f "SamAccountName=%s" -d -b "dc=company,dc=co,dc=uk" -D "cn=xxxxxxxx,cn=Users,dc=company,dc=co,dc=uk" -P -w "xxxxxxxx" -h "dc-1.company.co.uk" -p 3268 If I enter this from the command line, enter a suitable username/password then I get: user filter 'SamAccountName=xxxxxxxx', searchbase 'dc=company,dc=co,dc=uk' attempting to authenticate user 'CN=xxxxxxxx,CN=Users,DC=company,DC=co,DC=uk' OK Which seems great, but I can't get it to work in squid! Any ideas greatly appreciated! Thanks, Darren iCode Systems Ltd is registered in England. Company No. 3428325. VAT Reg. No. 699 4246 74
