Issue Summary

When Basic Authentication for API calls is disabled in Jira and a user tries to make an API call with this authentication method, the server responds with

{"message":"Basic Authentication has been disabled on this instance."} 

Steps to Reproduce

1. In Jira, navigate to Settings > System > Authentication Methods
2. Disable the feature "Allow basic authentication for API calls"
3. Fire an API call to Jira using Basic Authentication

Expected Results

Jira returns a generic error message so that a user isn't aware of the authentication methods allowed or disallowed on the system.

Actual Results

Jira fires a very specific error message

{"message":"Basic Authentication has been disabled on this instance."} 

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
