This section applies only if your TWiki is installed on a server that is both authenticated and on an intranet.
TWiki internally manages two usernames: Login username and TWiki username.
Login username: When you login to the intranet, you use your existing login username, for example pthoeny. This name is normally passed to TWiki by the REMOTE_USER environment variable. TWiki uses this name internally to log topic changes. Login usernames are maintained by your system administrator.
TWiki username: This is your name in WikiNotation, for example PeterThoeny, recorded when you register in TWikiRegistration; doing so also generates your personal home page in the Main web of your TWiki site.
TWiki can map the intranet username to the Wiki username automatically, provided that the Login username and Wiki username pair has been entered in the TWikiUsers topic. This happens automatically when you register.
NOTE:To correctly enter a WikiName - your own or someone else's - be sure to specify the Main web in front of the Wiki username: write Main.WikiUsername or %MAINWEB%.WikiUsername. This assures that the name will be linked automatically to the Main web, where user home pages are stored, even if the text is entered in a different web.
