+> **⚠️ NOTE ⚠️**  
+> An issue has been reported ([ansible/awx#10883](https://github.com/ansible/awx/issues/10883)) about LDAP authentication in AWX `19.3.0` which is mapped to AWX Operator `0.13.0`.
+> Use `0.12.0` (or a future release version with the problem fixed) instead of `0.13.0` if you plan to use LDAP authentication.
