Actually, looking back, the other DC had run fine, then it tried the one using rawUser, and produced the above message in the log, and gave me the following in my browser:

Web Login Service - Uncaught Exception

A software error was encountered that prevents normal operation:


org.apache.velocity.exception.MethodInvocationException: Invocation of method 'get' in class java.util.ArrayList threw exception java.lang.IndexOutOfBoundsException: Index: 0, Size: 0 at 0a54171e-a569-4cb4-8274-f1867fb1d3db[line 1, column 19]
