Have you ever set up the Enterprise release with OBIEE or another security model only to find something got screwed up and we have locked you out of Publisher? If so, read on ...
I have to thank Mike for digging up the solution. We use a configuration file to store security information including whether you want a local superuser or not. Its always a good idea to set this up no matter what the security model you want to use - company security policy not withstanding of course.
<property name="SUPERUSER_PASSWORD" value="admin"/>
<property name="SUPERUSER_USERNAME" value="admin"/>
<property name="GUEST_FOLDER" value="false"/>
<property name="ENABLE_SUPERUSER" value="true"/>
<property name="SECURITY_MODEL" value="XDO"/>
