Hello,
I have the same problem, how did you solve it?

This looks like it could be related to the LDAP search filter or the way the LDAP users are being returned. Since the log shows a “Bad search filter” followed by an invalid argument warning, I’d double-check the LDAP configuration and filter syntax first. Hopefully someone can help identify the exact setting causing it.

Check your LDAP user filter first. “Bad search filter” usually means the configured LDAP filter has invalid syntax—especially parentheses or an incorrect attribute. Verify the LoginLdap user search/filter settings and base DN.
