Is anyone having trouble with external customers logging into the portal for Service Management?

[Brad Hawkins]

We are setting up JIRA Service Management (server).  I did some testing on a cloud demo with success, but I'm having trouble authenticating as a customer with our server instance.  I have added the customer (via JSM customer management) and set my name and password as the customer (via the portal) but cannot log in. 

In my quest for a solution, I have found a few issues possibly related to Crowd vs JIRA internal authentication (we do use Crowd), but cannot seem to find a solution.  I have tried adding the customer manually in both Crowd and Internal directories but experience the same issue either way.  Can anyone help?
