A user with VisionFS Administrator privileges (also known as a VisionFS Administrator) is a Windows user who can run the VisionFS Profile Editor. The Profile Editor is restricted because it lets you grant access to any UNIX directory, even as root.
There must always be at least one VisionFS Administrator. A VisionFS Administrator is named during server setup; this user can add and remove other VisionFS Administrators using the Profile Editor.
All VisionFS Administrators must have valid UNIX accounts. The VisionFS Username Mappings database lets users -- including VisionFS Administrators -- have different usernames on Windows and UNIX. To run the Profile Editor, you log into Windows using the Windows username.
