Directory Utility shows user properties are set by XCreds for non-cloud user accounts

XCreds is settings values in Directory Utility for a local only user who signs in with the non-webview login screen. The XCreds menubar app considers these Directory Utility values to indicate that the user may be a cloud user who should be prompted to sign in because they do not have tokens. XCreds should not set these values for non-cloud users.

This issue can result in unexpected behavior for the shouldShowMenuBarSignInWithoutLoginWindowSignIn key.
