Active Directory authentication broken

Help
1

After last night updates, our Active Directory integration has broken:

[ERROR] Typed property LibreNMS\Authentication\ActiveDirectoryAuthorizer::$ldap_connection must not be accessed before initialization {“exception”:“[object] (Error(code: 0): Typed property LibreNMS\Authentication\ActiveDirectoryAuthorizer::$ldap_connection must not be accessed before initialization at /opt/librenms/LibreNMS/Authentication/ActiveDirectoryAuthorizer.php:231)”}

Tried to run daily.sh manually with no success.

Can you please have a look ?

Having the exact same issue here. I have 3 instances and only one was affected.

If you get this error, you are not on the monthly release, but the daily.
