A legacy security identity that originally represented a user stored in the PI User database in PI Server 3.4.380 and earlier. In PI Server 2010 and later, it became a special type of PI identity preserved for backward compatibility with older applications. It supports password-based authentication directly on the PI Server, but this method is the least secure and should be replaced with mappings to Windows identities.
