GSS_C_DELEG_POLICY_FLAG and cross realm

I've been working on the draft for GSS_C_DELEG_POLICY_FLAG lately. One thing I have added is th reason why we need this document. This was requested by reviewers.

Its for legacy deployments that can't update Kerberos today and can't/don't want to change behavior.

Getting the flag defined and the behavior clarified is only the first step of this process. The second is to make sure it works in the cross realm case too. The proposal I have is to make it an MUST that all intermediate cross realm tgt tickets also have ok-as-delegate flag set. It seems Microsoft does it that was and I've asked them if I've read their spec is correctly.

  2. This blog plays a crucial role in enhancing security and flexibility in cross-realm authentication scenarios. This flag, part of the Generic Security Service Application Program Interface (GSS-API), allows for the delegation of credentials based on policy, ensuring that only trusted entities can act on behalf of the user. In cross-realm environments, where authentication needs to be validated across different security domains, this feature is particularly valuable. It helps maintain a seamless and secure authentication process, enabling users to access resources in multiple realms without compromising security.

  3. Gsscdelegpolicyflagand cross-realm are concepts primarily used in the context of Kerberos authentication, particularly when dealing with distributed systems and secure communications across different domains. The GSS_C_DELEG_POLICY_FLAG allows for delegating authentication from one service to another, enabling secure, seamless communication without repeatedly asking for credentials, which is vital for complex enterprise environments. The cross-realm functionality enhances Kerberos by allowing trust relationships between different realms, facilitating authentication across domains.
