What does it mean when trying to login and its receiving a “realm is disable” error?
This error message indicates that the application does not have the specified realm enabled or possibly that a realm has been specified which does not exist. The full error message and/or event from your tenant logs likely provides additional details regarding which realm resulted in the error occurring. It will need to be a connection type which uses username and password to authenticate, such as a database connection.
Please check your connection and application settings to ensure that it is enabled.
