Odd logging if user not in authorized group

[marohrdanz]

If a request is sent for a user and a group for which the user is NOT a member, the server log includes a note that a token was generated. For example:

INFO ldap-jwt: Token generated for '<username>' with groups ''. JWT expires: <exp date>

The correct response is returned (a 401: Unauthorized). The issue is the misleading log message.
