Authentication
So turns out that AppID is not what I need. There is an third party IAM service called Passport but it doesn't fall under the free IBMer Bluemix plan. It has a 14 day trial but that obviously won't work. I really need authentication and I really don't want to write reams of code to implement it.
Looking outside Bluemix, I came across JumpCloud LDAP-as-a-Service. They offers a free plan for max of 5 users so I'll give it a try.
