Sam Saffron 7b17eb06da FEATURE: ban any SSO attempts with invalid external id
We now treat any external_id of blank string (" " or "     " or "", etc) or a
invalid word (none, nil, blank, null) - case insensitive - as invalid.

In this case the client will see "please contact admin" the logs will explain
the reason clearly.
