[jboss-user] [JBoss Portal] - Hibernate exception when using the JBoss Portal Identity Man

[npillingcorda]

JBoss Portal Version: 2.6.4
Did you get Portal from CVS? or download it? downloaded jboss-portal-2.6.4-bundled.zip
OS Platform: Linux Fedora Core 4
JVM 1.5.0_11

I'm trying to use the JBoss Portal Identity Management API to get information about the logged-in user from JBoss Portal in a portlet. The API is described on: http://docs.jboss.com/jbportal/v2.6.4/referenceGuide/html/identity.html. 

I'm getting the following stack trace:
2008-02-25 10:58:11,521 ERROR [org.jboss.portal.identity.db.HibernateUserModuleImpl] Cannot find user by name admin

Am I doing something wrong or is there a problem I need to work around?
