I am having issues to override superset\u2019s custom security manager. I have the following code in my config.py\n```\nfrom superset.security import SupersetSecurityManagerclass CustomSecurityManager(SupersetSecurityManager):\n     def __init__(self, appbuilder):\n         super(CustomSecurityManager, self).__init__(appbuilder)\n\n     def add_user(self, username, first_name, last_name, email, role, password="", hashed_password=""):\n       if not email.endswith("@abc.com"):\n           raise Exception()\n       if len(password) &lt; 8:\n           raise Exception()\n       return super().add_user(self, username, first_name, last_name, email, role, password, hashed_password)\n\nCUSTOM_SECURITY_MANAGER = CustomSecurityManager```\nI do not see anything the logs, but the above validation is not working I think. I am able to register a user with password length less than 5. I am using v0.30. Thanks <@U89DGH27L> for the code.\nDo anyone here see any obvious mistake I am making here?
