You should switch to 1.5.4. 1.5.0 is pretty old and buggy ...

That should not be a problem.

The 'userName' is not a default attributyeType. Only attributeType can 
be indexed. However, you should not get a NPE, so I suggest you check if 
you still get a NPE with 1.5.4, and if so, fill a JIRA.

If you have created a specific schema, it would be usefull to tell us 
how you created it, and to give us its content.
