     SYNOPSIS
          auth/changeuser [-np] user

          auth/wrkey

          auth/convkeys [-p] keyfile

          auth/printnetkey user

          auth/auth.srv

          auth/guard.srv

     DESCRIPTION
          These administrative commands run only on the authentication
          server.  Changeuser manipulates an authentication database
          file system served by keyfs(4) and used by file servers.
          There are two authentication databases, one holding informa-
          tion about Plan 9 accounts and one holding SecureNet keys.
          A user need not be installed in both databases but must be
          installed in the Plan 9 database to connect to a Plan 9 ser-
          vice.

          Changeuser installs or changes user in an authentication
          database.  It does not install a user on a Plan 9 file
          server; see fs(8) for that.

          Option -p installs user in the Plan 9 database.  Changeuser
          asks twice for a password for the new user. If the responses
          do not match or the password is too easy to guess the user
          is not installed.

          Option -n installs user in the SecureNet database and prints
          out a key for the SecureNet box.  The key is chosen by
          changeuser.

          If neither option -p or option -n is given, changeuser
          installs the user in the Plan 9 database.

          Changeuser prompts for biographical information such as
          email address, user name, sponsor and department number and
          appends it to the file /adm/netkeys.who or /adm/keys.who.

          Wrkey prompts for a machine key, host owner, and host domain

          and stores them in local non-volatile RAM.

          Convkeys re-encrypts the key file keyfile. Re-encryption is
          performed in place.  Without the -p option convkeys uses the
          key stored in /dev/keys to decrypt the file, and encrypts it
          using the new key.  By default, convkeys prompts twice for
          the new password.  The -p forces convkeys to also prompt for
          the old password.  The format of keyfile is described in
          keyfs(4).

          Printnetkey displays the network key as it should be entered
          into the hand-held Securenet box.

          Status is a shell script that prints out everything known
          about a user and the user's key status.

          Auth.srv is the program, run only on the authentication
          server, that handles ticket requests on IL port 566.  It is
          started by an incoming call to the server requesting a con-
          versation ticket; its standard input and output are the net-
          work connection.  Auth.srv executes the authentication
          server's end of the appropriate protocol as described in
          auth(6).

          Guard.srv is similar.  It is called whenever a foreign (e.g.
          Unix) system wants to do a SecureNet challenge/response
          authentication.

     FILES
          /adm/keys.who     List of users in the Plan 9 database.
          /adm/netkeys.who  List of users in  the SecureNet database.
