First, thanks a lot for all replies to my question.
I find the this way to be the simplest.
(Please let us know if you see any problems with this solution)
1. Download and compile the attached code (rename to .java)
2. Deploy .class to $CAS_HOME/WEB-INF/classes (in this case to package
'classes/se/gu/cas/')
3. Edit $CAS_HOME/WEB-INF/deployerConfigContext.xml
Comment out:
<bean
class="org.jasig.cas.authentication.principal.UsernamePasswordCredentialsToPrincipalResolver"
/>
Replace with our new bean:
<bean
class="se.gu.cas.CustomUsernamePasswordCredentialsToPrincipalResolver" />
4. Restart server and test!
Done!
