1. Install and configure the OpenSSO server and create a new subject there: "test2"
2. On Liferay, configure the various URLs for OpenSSO & enable it within Portal Instance
3. Assert that the "First Name Attribute" default value is "givenname" (from the metatype)
4. Attempt to log into the Liferay. It should redirect to the OpenSSO server where you will authenticate as test2

Expected result: A new Liferay user is created for test2 and you are logged in as it
Actual result: An error is logged and you are not logged in.

See log error below. It is caused by the incorrect default value in step 3. It should be "givenName".
