I am wondering if someone can help clarify something for me.

I have been reading the documentation regarding authentication and
security in Fedora and in the sample policies from this page
http://www.fedora.info/download/2.2/userdocs/server/security/xacml-policies/examples/example-repository-policies/apia-tighten-defaults/apia-restrict-all-methods/deny-apia-if-not-tomcat-role.xml
it has this info below which mentions the tomcat-users.xml

"<Policy PolicyId="deny-apia-if-not-tomcat-role"
RuleCombiningAlgId="urn:oasis:names:tc:xacml:1.0:rule-combining-algorithm:first-applicable"
xsi:schemaLocation="urn:oasis:names:tc:xacml:1.0:policy
http://www.fedora.info/definitions/1/0/api/cs-xacml-schema-policy-01.xsd";>
−
        <!--

*********************************************************************************************************************************************************
-->
−
        <!--
  This policy will DENY access to ALL API-A methods to users who are
NOT in the administrator or professor ROLES. 
-->
−
        <!--

*********************************************************************************************************************************************************
-->
−
        <!--
  NOTE:  User ROLES are defined using custom Fedora attributes in the
tomcat-users.xml file. 
-->
−
        <!--
  See the Fedora system documentation on Tomcat Authentication for
details of how to specify custom attributes 
-->
−
        <!--
  (such as 'fedoraRole') in the tomcat-users.xml file. 
-->
−
        <!--

When I read the documentation for Fedora 2.2 (
http://www.fedora.info/download/2.2/userdocs/server/security/AuthorizationXACML.htm#ATTR
) though there is no mention of tomcat-users.xml but does mention the
fedora-users.xml.  

Should the above sample policy refer to the fedora-users.xml instead of
tomcat-users.xml?

The documentation for Fedora 2.1
http://www.fedora.info/download/2.1b/userdocs/server/security/AuthorizationXACML.htm#ATTR
does mention the tomcat-users.xml.  Is that still valid in 2.2?

My real question is can Fedora use container based security or is it
just reading these xml files to get user/role info?  

We are developing a Drupal module as a frontend for Fedora and we are
thinking that a custom realm for tomcat that actually uses drupal's
database to determine roles etc,. instead of the tomcat-users.xml or the
fedora-users.xml file may solve some of our problems.

Thanks,
