LDAP Group Authentication

[corsino]

I´ve Cacti 0.8.7g on Debian Lenny. I´m trying to use LDAP Group Authentication, but with no success. Wheny I use the "Require Group Membership " option and try do log in, I receive the message "LDAP Error: Insuffient access". The user is in the group. I only log with LDAP Authentication with group merbership disabled and with mode "No Searching".
Anyone have any idea to help me?
