       edauth  -  update  and  list  authentication and capabilities (authcap)
       database information (Enhanced Security)

       /usr/tcb/bin/edauth [-d db] [-L	| -N  | -S source]  [-q]  [-v]	entry‐

       /usr/tcb/bin/edauth  -g	[-d db] [-L  | -N  | -S source] [-q] [-t] [-v]

       /usr/tcb/bin/edauth -s  [-d db] [-L  | -N  | -S source] [-R]  [-t]  [-U
       uid] [-C] [-q] [-v]

       /usr/tcb/bin/edauth  -r	 [-d  db]  [-L	 |  -N	| -S source] [-q] [-v]

       /usr/tcb/bin/edauth -H

       Specifies which database to use.	 Select from one of the characters  d,
       f, p, t, or v.

	      d -  The system default database, /etc/auth/system/default

	      f -  The file control database, /etc/auth/system/files

	      p	   -	User   profile	 data	in   the   /tcb/files/auth.db,
	      /var/tcb/files/auth.db, and optional associated NIS map sources.

	      t -  The terminal control database, /etc/auth/system/ttys.db

	      v -  The terminal control database, /etc/auth/system/devassign

	      The user profile database (p) is the default if no -d option  is
	      given.  Gets the named entries (or all) and prints them to stan‐
	      dard output rather than editing them. If the -q option  is  also
	      given,  the  entries are not printed, and the exit status is the
	      only confirmation of whether at least one entry would have  been
	      printed  if  -q had not been specified.  Removes (deletes) named
	      entries rather than editing them.	 Sets new values based on pre-
	      edited entries read from standard input. If a new entry is being
	      created, the corresponding passwd entry must be  created	first.
	      If  the -C option is not given, existing entries are overwritten
	      by the new data.	When used with -g or -s options, account  tem‐
	      plate  entries are included in addition to user-profile entries.
	      Note that account templates do not have passwd  entries.	 Gives
	      more  verbose messages.  Restricts the -s option to creating new
	      entries only, rather than possibly  overwriting  existing	 ones.
	      Uses  only  local	 entries, not NIS.  Uses only NIS entries, not
	      local.  Causes new local user-profile entries to be  written  to
	      the  root partition only, no matter what the UID of the profile.
	      Restricts database operations to the specified data  source,  as
	      determined  by the /etc/nsswitch.conf file.  Specifies the mini‐
	      mum general user UID.  User-profile entries with UIDs less  than
	      this value (default of 100) are written to the root partition in
	      the /tcb/files/auth.db file.  Profiles with uids greater than or
	      equal    to   the	  specified   value   are   written   to   the
	      /var/tcb/files/auth.db file.  Print a help message and exit suc‐
	      cessfully with no further processing.

       The  edauth  utility displays and modifies the system databases used by
       the enhanced security subsets. These include the user profile databases
       and their NIS map source files, the file control database, the terminal
       control and device assignment databases, and the system	default	 data‐
       base. Note that edauth does not alter /etc/passwd.

       The  edauth utility is intended for disaster-recovery situations, since
       the GUIs provide a much friendlier interface. However, for sites	 where
       X is not available, edauth can be used for general maintenance of these

       If none of the -s, -g, or -r options are given,	edauth	extracts  each
       matching	 entry into a temporary file, and allows the user to edit that
       entry.  If the edited entry has more unparsed fields than did  the  old
       copy,  a	 warning  is  given.  If the -v option was given, the unparsed
       text is displayed.

       Editing and setting of entries in NIS maps is only allowed on  the  NIS
       master  host,  in which case the changes are made to the NIS map source
       files themselves, and a make of the  NIS	 maps  is  then	 performed  by

       The  only  option  available  to a non-root user is displaying the pub‐
       licly-accessible databases or the user's own profile.

       Use of the -S source option requires that the named source be specified
       by  the	/etc/nsswitch.conf  file  for  the  affected database. It also
       requires update access to the nsswitch--served data. This  is  in  con‐
       trast  to  how -L and -N work, since those options work to set up data‐
       bases before the relevant system daemon () is running.	In  all	 other
       respects, -L is equivalent to -S files, and -N is equivalent to -S nis.

       The  following environment variables can be used by edauth: Checked for
       being set only, in order to determine whether the  $VISUAL  environment
       variable should be consulted to find an editor to use.  The $TERM vari‐
       able is also likely to be used by the editor that is spawned.   Checked
       to  find	 the editor to use when editing data, if the $TERM environment
       variable is set.	 Checked to find the editor to use when editing	 data.
       If  neither  the $VISUAL nor the $EDITOR environment variable is avail‐
       able, edauth checks /usr/bin/ex and /sbin/ed  for  execute  permissions
       and stops attempts to edit data if none can be found.

       Other  environment variables which are likely to be used: This environ‐
       ment variable is checked by the /var/yp/Makefile file when updating the
       NIS  maps  in order to determine whether to force the NIS slave servers
       to update their maps immediately (and to wait for that update).

       To display just the wildcard entries from the ttys and devassign	 data‐
       bases: # edauth -g -dt '*' '*:*' # edauth -g -dv '*' '*:*'

       To display the system defaults data: # edauth -g -dd

       For a non-root user to display his or her own profile: % edauth -g

       For a privileged user to display all user profiles: # edauth -g

       To display the user profile for root: # edauth -g root

       To edit the entry for user root: # edauth root

       To edit the ttys database entry for lat/628: # edauth -dt lat/628

       To edit the NIS profile entry for user nobody: # edauth -N nobody

       An  alternative	way  to	 edit the NIS profile entry for user nobody: #
       edauth -S nis nobody

       To add a template of cis401 to a list of user names contained in a file
       named students: edauth -g `cat students` \
	   | sed 's/:chkent:/:u_template=cis401:chkent:/' \
	   | edauth -s

       Commands: convuser(8), convauth(8), authck(8)

       Files:  authcap(4),  prpasswd(4),  ttys(4),  default(4),	 devassign(4),
       files(4), nsswitch.conf(4)
