2 Kerberos Authentication for Multi-organization

3 Cross-Realm Kerberos Authentication User sent request to local Authentication Server Local AS shares cross-realm key to verifier's authentication server(VAS) Local AS sent TGT to client User request a session key with his/her TGT VAS Lookup the cross-realm key The VAS grant client with the session key

4 Authorization with Kerberos Kerberos does not itself provide authorization, but V5 Kerberos passes authorization information generated by other services. In this manner, Kerberos can be used as a base for building separate distributed authorization services. (implement in the future)

5 Authorization structure
