Grouper Users - Open Discussion List

[Travis Schmidt <>]

I only needed to add the CAS jars and change the context in server.xml to this:

        <Context docBase="/ucd/opt/grouper-ui/build/grouper" path="/grouper"

                  reloadable="false"

                  mapperContextRootRedirectEnabled="true"

                  mapperDirectoryRedirectEnabled="true">

          <Realm

             className="org.jasig.cas.client.tomcat.v7.PropertiesCasRealm"

             propertiesFilePath="/etc/tomcat/grouper-users.properties"

          />

          <Valve

            className="org.jasig.cas.client.tomcat.v7.Cas20CasAuthenticator"

            encoding="UTF-8"

            casServerLoginUrl="https://ssodev.ucdavis.edu/cas/login"

            casServerUrlPrefix="https://ssodev.ucdavis.edu/cas/"

            serverName="grouperdev.ucdavis.edu"

          />

          <!-- Single sign-out support -->

          <Valve

            className="org.jasig.cas.client.tomcat.v7.SingleSignOutValve"

            artifactParameterName="SAMLart"

          />

       </Context>

We restrict who can access by the grouper-users.properties that has has format 

LOGIN_ID=grouper_user

I didn't change anything else in the grouper properties or configuration, but did need to make sure that the user logging in was able able to be searched by a source that was configured in sources.xml

Hi Chris 

 

Thanks, yes we did add the cas jars to the tomcat library. 

 

I think we need some kind of security restraint in web.xml for cas, but I’m not sure what.  When some entries are there, it will go out to CAS to authenticate, but if I strip them all, then I never see CAS and I get the not-authenticated error.

I assume you added the cas jars to the tomcat library dir?

 

Does someone know if you need security constraints in web.xml for cas?

 

Maybe you could ask this on a CAS mailing list if someone here cannot help?

 

Thanks

Subject: [grouper-users] Grouper CAS -Shib authentication

 

Hi folks.

 

I’m working on this CAS authentication piece for grouper 2.3 again, and I am still stuck.  Here’s the current status. 

 

I removed the security constraints from web.xml files:

 

/grouper/grouper.ws-2.3.0/grouper-ws/webapp/WEB-INF/web.xml

/grouper/grouper.ui-2.3.0/dist/grouper/WEB-INF/web.xml

 

 

 

Now when I hit the url, I don’t seem to get redirected to CAS/Shib.  I don’t get the tomcat 403 error, but the application errors:

 

 

 

 

Anything else I can provide to help troubleshoot?  Again, thanks for all the help.
