As an administrator I want to reveive an informative error message when logging in with wrong user account so that solving understanding the cause of the problem would be easier

Problem

If Security Server has not been initialized yet, logging in with user account other than Web Admin UI (other Unix user) causes "Fatal system error" and no further information about the problem gets logged. After the Security Server has been initialized it's still possible to login with wrong user account, but the error message is bit more informative "Not authorized".

Acceptance criteria

• Descriptive and informative error message is returned when user tries to login with user account that does not belong to X-Road specific groups
