I have an issue since I have install 9.192 (from 9.191), LDAP authentication failed each time.
The LDAP server is an AD, we did not make any modification on this server since several weeks.
I put the aua in debug mode and it seams the bindDN is missing during the LDAP request :
aua[13290]: id="3007" severity="debug" sys="System" sub="auth" name="Entering do_auth_directory: server=X.X.X.X port=389 ssl=0 bind_dn=ldapreader base_dn=DC=domain,DC=local"

The "test server settings" works fine.
The "authenticate example user" does not work.
I think in the bind_dn field is not expected to be empty, could you check with your UTM if this field is also empty ?
