Authentication with LDAP


I using McAfee Web Gateway 7 and OpenLdap for Authentication users (please see rule in attachment). I have 2 problems:

+ When users access to web the authentication box always appears (ask username and password), although this user loged into LDAP

Please help me fix the problem

Thank and Regards,
