I am currently trying to enable a spnego based SSO Application. As part of this I seek to get the delegated credentials.

How to verify that the credential I get after GSSContext.acceptSecContext(gss, 0, gss.length); is a delegated credential or not. GSSContext.getCredDelegState() is true.

My primary doubt is whether the server principal in the ticket should be krbtgt/ABC.XYZ.COM@ABC.XYZ.COM or should be the service (HTTP/host.ABC.XYZ.com) for which the ticket was delegated?``

Delegated Credential is.....[GSSCredential:

I am using a linux based KDC and linux hosts for this.

Is there any reference to what the delegated ticket should be like?

已为您机器的 UPN 创建了委托票证，如果您使用 MIT/Heimdal KDC（没有经验），它可能是host/fqdn@REALM. 在 Windows (AD KDC) 中，它是 hostname$@REALM. 只有该机器能够提取委托凭证。

委托凭证的全部意义在于，最终服务的委托凭证和初始凭证之间应该没有区别。
