+Well, on such a private wiki, one can neither register herself nor
+reset his password: the registration page, as any other page, would be
+forbidden to non-authenticated users. Admin users should then be
+enabled to:
+
+- register a new user
+- reset someone else's password
+
+In both cases, a brand new random password is sent by e-mail to the
+new user.
+
+An authenticated user should nevertheless be able to change his
+own password. -- [[intrigeri]]
