Error When Publishing

I'm having a problem getting a new install of Nuxeo working.  My setup is:
Windows Server 2003
MS SQL Server 2005
Nuxeo EP 5.1.6
JDK 1.5.17

When trying to publish a document as any user except Administrator, I get the error:
ERROR [org.apache.catalina.core.ContainerBase.[http://jboss.web].[localhost|http://www.nuxeo.org/discussions/].[/nuxeo].[Faces Servlet]|http://www.nuxeo.org/discussions/] Servlet.service() for servlet Faces Servlet threw exception
org.nuxeo.ecm.core.api.DocumentSecurityException: Privilege 'ReadChildren' is not granted to 'Assistant1'

The user has full permissions to the document, workspace, and section.  The only changes I've made from the base install is switching the database to MSSQL.
