Vulnerability discussion

An exportable version of credentials is provided to remote hosts when using credential delegation which exposes them to theft on the remote host. Restricted Admin mode or Remote Credential Guard allow delegation of non-exportable credentials providing additional protection of the credentials. Enabling this configures the host to support Restricted Admin mode or Remote Credential Guard.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
