Version

Expected Behavior

A warning would be logged if the defined org within the github connector does not match the case used in the login name (as returned by the github api).

Actual Behavior

Defining A1Example in the config when the org name is a1example will allow successful authentication but with an empty group list, and subsequently fail to apply any group specific access policies.
