CAS relative redirect

[Kevin Liu]

Is it possible for the cas filter to redirect with a relative path to the entry point? For example if I hit cas1.com and set my redirect to /cas1 it would redirect to cas1.com/cas1 instead of localhost/cas1.

Kevin,

Are you trying to run two instances of CAS on the same machine/tomcat?

That is, why do you want to change the URL from /cas to /cas1?

Hello Ray,

No it's like this. I currently have cas deployed within a container sitting behind a reverse proxy. When users use a webapp without authentication, they will get redirect to dnsname.com/cas endpoint on the proxy which will then send them to cas. The problem is the dnsname.com will be dynamic based on the deployment environment. So I was hoping to have a cas filter where it'll just append /cas to the incoming request dnsname.

Kevin,

Could the deployment process create a properties file with a value set for dnsname?

In properties file:

cas.server.url={dnsname}/cas

In application context or where ever the filter is defined:

    <bean name="authenticationFilter"

          class="org.jasig.cas.client.authentication.AuthenticationFilter">

        <property name="casServerLoginUrl" value="${cas.server.url}/login" />

        <property name="serverName" value="{servicehost}" />

    </bean>

Ray,

Can cas.properties pick up env variables? That could work in that case.

Kevin,

You can set environment variables on the command line (-Dvar=blah) and in tomcat/bin/setenv.sh.

How hard would it be to modify the filters to include relative redirect paths?

Filters, in general, are 'relatively simple'. Take a look at https://github.com/apereo/java-cas-client
