Hello, sorry for my bad english. Current user authentication schema: ================================================================================== 1.browser --> 2.(encoding only, but need encryption) --> 3.squid_ldap_auth --> 4.LDAP over SSL --> 5.LDAP server ================================================================================== While searching squid mail archive, I understood that client authentication with SSL encryption is not possible for now, because browsers still don`t support this function and it is impossible to connect LDAP server via "squid_ldap_auth" or "squid_ldap_group" using digest user authentication too. But last discussion found by me was dated 2004 year. Maybe there is any method now that can help me to solve this problem? Thanks. -- With best regards, Vladimir.
