Hi Chad,
CAS is working with our Grouper 2.4 instance. Thanks for your help with this. Logout is working.
I did not need the extra cas directory cas/index.jsp so I didn't need steps 2a, 2b, and 3.
I removed the security constraints from web.xml since those were preventing access. I think those came from web.core.xml.

  <security-constraint>
    <web-resource-collection>
      <web-resource-name>UI</web-resource-name>
      <url-pattern>/grouperUi/app/*</url-pattern>
    </web-resource-collection>
    <auth-constraint>
      <role-name>grouper_user</role-name>
    </auth-constraint>
  </security-constraint>
  <security-constraint>
    <web-resource-collection>
      <web-resource-name>UI</web-resource-name>
      <url-pattern>/grouperUi/appHtml/*</url-pattern>
    </web-resource-collection>
    <auth-constraint>
      <role-name>grouper_user</role-name>
    </auth-constraint>
  </security-constraint>
  <security-constraint>
    <web-resource-collection>
      <web-resource-name>UI</web-resource-name>
      <url-pattern>/grouperExternal/app/*</url-pattern>
    </web-resource-collection>
    <auth-constraint>
      <role-name>grouper_user</role-name>
    </auth-constraint>
  </security-constraint>

I will need to merge those changes into /var/grouper/installGrouper2.3/grouper.ui-2.3.0/webapp/WEB-INF/web.core.xml
and then rebuild ("ant war") and copy the new web app to the Tomcat directory. Is that right?

I'm hoping we can move away from the custom classes and ant config -- the Java classes are from 2009 and specific to the older UI that isn't in use. Ideally it would be a change in web config, and adding an additional library.

I was able to get something working locally. It's using a 4.0 cas server and 3.5 client library, so YMMV. Here is what I did.

1) Downloaded cas-client-core (latest 3.5.1) and put into WEB-INF/lib; source either from from Maven (https://search.maven.org/search?q=g:org.jasig.cas.client%20AND%20a:cas-client-core&core=gav) or from mvnrepository site which has ads (https://mvnrepository.com/artifact/org.jasig.cas.client/cas-client-core)

2a) Copied webapp index.jsp to cas/index.jsp

2b)* Edited paths in cas/index.jsp, to reference parent directory instead of the current one

    <%@ include file="../WEB-INF/grouperUi2/assetsJsp/commonTaglib.jsp"%>
    String location="../grouperUi/app/UiV2Main.index?operation=UiV2Main.indexMain";


3)* Added to WEB-INF/classes/Owasp.CsrfGuard.overlay.properties

  org.owasp.csrfguard.unprotected.CASLogin=%servletContext%/cas/*

4) Added to WEB-INF/web.xml, changing parameters as needed. Based on https://apereo.atlassian.net/wiki/spaces/CASC/pages/103252594/Configuring+the+Jasig+CAS+Client+for+Java+in+the+web.xml

</filter-mapping>


5) Start Tomcat, check catalina and localhost logs if any startup errors

6) Go to http://localhost:8080/grouper/cas/index.jsp


~~~~~

*I initially tried to set up a copy of index.jsp as cas.jsp in the top level of the webapp, so that the paths did not need to be adjusted in the file. It sometimes worked, but other times it gave an error page. The times it failed were when there was no existing webapp session, so it appended ";jsessionid=.." after the URL. Somehow that broke the CSRFGuard exception, even if I put in wildcards that should have matched. If someone understands the subtlety there, I'd be interested in knowing.

The logout seems to be doing the right thing, and clearing out the session including the authentication. I haven't tested inactivity timeouts so that is still unverified.

My institution isn't using CAS, so this was just a proof of concept. If this works for you with some other adjustments, let us know and we can update our documentation.

-Chad

We're about to embark on upgrading to 2.4 from 2.2, and we rely on CAS AuthN. Hopefully this can be sorted out!
