If a user is assigned a UID that is in the reserved range, even if it is not presently in use, security exposures can arise if a subsequently installed application uses the same UID.

Check content

Fix text

The root role is required. Correct or justify any items discovered in the Check step. Determine if there are any accounts using these reserved UIDs, and work with their owners to determine the best course of action in accordance with site policy. This may require deleting users or changing UIDs for users.

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.
