Ldap 389-directory console doubt?

Hi all,

In my Centos 6.5, I have configured 389-directory server for Fortigate Firewall user Authentication to access the INTERNET.

In Firewall LDAP server connection is successfully configured and all the users are imported to the USER Authentication.

In client if the user trying to open the www.google.com it automatically redirect to the Firewall User Authentication, if I enter the Ldap user name & password the authentication is failed I dont know why, but the all the configuration are successful.

Anyone please give me suggestion to resolve this issue.

No all the users are accessing the INTERNET without any authentication, but I want to enable the User Authentication.

Thanks in Advance
