After connecting to the Content Analysis System appliance over SSH and attempting to create an API key we face an error relating to the API key not being able to be created for the specified user.
CAS 2.4.x
An API key cannot be created for the specified user (testuser2)
CAS 2.3.x
405 Client Error: Method Not Allowed for url: http://localhost:9080/rapi/system/users/api_keys
In order to create an API key on the CAS appliance the specified username has to exist locally on the appliance as we're mapping the API key to that particular users profile.
We will need to create the user locally on the CAS.
