Active Directory auth Enable, show users but unable to login in UCP

as in title i’ve this problem.
I’ve set, suppose correctly, the authentication via AD and in users i can see the list of all users in domain but when i try to login into UCP with my credential i receive a login incorect.
The credential are right at 100% because I use use them every day to login in my pc.
If in shell i try to do “fwconsole userman sync” the message “Starting Sync…” still there even.
If i make a telnet on port 389 into domain server it’s work fine.
Thanks in advance
Freepbx versio is 13.0.84

Did you grant your user(s) permission to log into the UCP?
