CAS Server Delegate authentication to another CAS Server

[Wang David]

Hi,

Try to configure cas server to delegate authentication to another cas server. Current use CAS 5.1 and another server is also CAS 5.1. Following the configuration provide in the document. But the application got authentication error. Check the cas server log, found the authentication successfully. the second CAS Server did the authentication and reture TGT and ST.  But the application display the authenicaiton failed.  It seems the first CAS Server delegate the authentication to second CAS server, and the result is OK, but for some reason the first CAS server return TGT and ST to app got something wrong.  Since there are not much configuration parameters to configure. Don't know why? 

the following is configure on the CAS Server that do the delegation:

cas.authn.pac4j.typedIdUsed=false

cas.authn.pac4j.autoRedirect=false

cas.authn.pac4j.name=CasServerClient

cas.authn.pac4j.cas[0].loginUrl=https://sso.abc.com:8443/cas/login

cas.authn.pac4j.cas[0].protocol=CAS30

# (Optional) Friendly name for CAS, e.g. "This Organization" or "That Organization"

cas.authn.pac4j.cas[0].clientName=CasServerClient

Any Help

Thanks
