LDAP users can't login from GUI

[l.ansaloni]

I use the version :
OPNsense 20.1.8_1-amd64
FreeBSD 11.2-RELEASE-p20-HBSD
LibreSSL 3.0.2

I have setup the LDAP server for opnsense Web GUI login by using the step from documentation:
https://docs.opnsense.org/manual/how-tos/user-ldap.html
with Read properties and Synchronize groups option active in LDAP server setting.

User import to local users database with success.
User assign to local admins group with success.
From the console:

Code: [Select]

root@firewall:~ # cat /etc/group
...
admins:*:1999:root,l.ansaloni
...
When I test the user authentication in System\Access\Tester, everything find and no error.
I got the result message:
This user is a member of these groups:
admins

When I try to login in the Web GUI, I loop in the login page and the user has being kick out of the admins group.
from the console:

Code: [Select]

root@firewall:~ # cat /etc/group
...
admins:*:1999:root
...
Do anyone have the same problem?
