STATUS_LOCAL_USER_SESSION_KEY

A local RPC session key is not unique

This informational status is security-context related. It tells the caller that the session key returned for a local RPC connection is a constant local value, not unique material negotiated for a remote protected channel.

Do not use this as proof that a network authentication handshake occurred. For code that needs channel binding, sealing, signing or peer identity, inspect the actual RPC security level and authentication service rather than assuming the session key is sufficient.

What to inspect

  • Determine whether the RPC call is local or remote.
  • Inspect requested RPC authentication, impersonation and protection levels.
  • Avoid deriving authorization decisions from the constant local-session-key behavior.
