[cas-dev] Update to yale Java client to accept attributes

[Sean R. McNamara]

Hi all,

I modified the Yale 2.1.1 CAS client to accept attributes handed back by 
the CAS server.

It will accept anything in the serviceResponse formatted such as:

<cas:serviceResponse xmlns:cas='http://www.yale.edu/tp/cas'>
    <cas:authenticationSuccess>
        <cas:user>Sean R. McNamara</cas:user>

                <cas:attribute name="loginType" value="USERPASS"/>
                 
                <cas:attribute name="name" value="Sean R. McNamara"/>
           
                <cas:attribute name="affil" value="DART"/>
       
    </cas:authenticationSuccess>
</cas:serviceResponse>

and make the values available in the session named as:

edu.yale.its.tp.cas.client.filter.attribute.<attribute name>
e.g. edu.yale.its.tp.cas.client.filter.attribute.name or 
edu.yale.its.tp.cas.client.filter.attribute.affil or 
edu.yale.its.tp.cas.client.filter.loginType (from the above example)

it also makes a HashMap available of all the values at 
edu.yale.its.tp.cas.client.filter.attribute

Another feature I added was to allow the filter to override the value of 
edu.yale.its.tp.cas.client.filter.user in web.xml

by setting an init-param such as:

        <init-param>
          
<param-name>edu.yale.its.tp.cas.client.filter.idattribute</param-name>
          
<param-value>edu.yale.its.tp.cas.client.filter.attribute.name</param-value>
        </init-param>

I would like to contribute this code back to the project.  How should I 
go about this?

Thanks!

..Sean.
