Ldap realm problem

Hi all, i try to configure a ldap realm on payara 5 to authenticate my web application using form method.
The problem is that after a login success, using ldap user, on server console i have an error 403.
If the user isn’t in LDAP i have an error “user not found”.
I try a lot of conbination ldap groups and users but i can’t find a solution.
Have you a suggestion for my problem?
Many thanks.
