Using Technology Innovation to Meet Security Needs WAS v7 Offers Expanded Security Auditability (continued) Leveraging Auditability 35 2007 IBM Corporation
Using Technology Innovation to Meet Security Needs WAS v7 Enhances Kerberos Authentication and Single Sign-on (cont.) WAS v7 Kerberos (SPNEGO) Flow 1. The client sends an HTTP/Post/Get/Web-Service request to WAS. 2. WAS returns HTTP 401 Authenticate/Negotiate. 3. The client obtains a Ticket Granting Ticket (TGT). 4. The client requests a Service Ticket (TGS_REQ). 5. The client obtains a Service Ticket (TGS_REP). 6. The client sends HTTP/Post/Get/Web-Service and an authorization SPNEGO token to WAS. 7. WAS validates the SPNEGO token. If the validation is successful, it retrieves the user ID, the client Kerberos ticket and the GSS delegation credential from the SPNEGO token. 8. WAS validates the user ID with the WebSphere user registry and creates an LTPA token. 9. WAS returns HTTP 200, content and the LTPA token to the client 36 2007 IBM Corporation
