ypmixer(1M)                                                     ypmixer(1M)

NAME
     ypmixer - update /etc/passwd, /etc/shadow and /etc/group from the NIS
     maps (old procedure)

SYNOPSIS
     /var/yp/ypmixer -c map [-t tofile] [-s shadowfile] [-a] [-v] [-f]
                     [-N | -C]

DESCRIPTION
     The ypmixer command updates the local /etc/passwd and /etc/shadow or
     /etc/group files from the NIS server maps.

     Commands and library functions in Reliant UNIX do not generally access
     the NIS server if they are reading or modifying data from /etc/passwd,
     /etc/shadow or /etc/group. The global user and group entries are
     therefore merged in the local files.

     This occurs periodically with NIS clients or, in the case of auto-
     update clients, at the instigation of the network administration host.
     Proxy hosts and the network administration host always update their
     own local files if the maps are created again on the network adminis-
     tration host following changes to the ASCII source files
     (/etc/yppasswd or /etc/ypgroup).

OPTIONS
     -c map
          map can be passwd or group. In the case of passwd, the local
          /etc/passwd and /etc/shadow files are updated, and in the case of
          group the local /etc/group file.

     -t tofile
     -s shadowfile
          The global and local user entries are merged temporarily in
          /etc/ptmp, shadow entries in /etc/stmp, and the group entries in
          /etc/gtmp. The temporary files are copied to /etc/passwd,
          /etc/shadow or /etc/group when the merge process has ended.

          This option allows other names to be specified for the temporary
          files.

     -a   The merge process takes account of /var/yp/pwpattern as it is
          carried out.

     -v   ypmixer outputs messages to support testing.

     -f   The merge process also takes place if the local file is newer
          than the NIS map.

     -N   The name of the home directory of a global user is transferred
          unchecked to the local user entry.

ypmixer(1M)                                                     ypmixer(1M)

     -C   The home directory of a global user is produced if it does not
          yet exist and the global user entry is transferred to the local
          /etc/passwd file.

     ypmixer is generally invoked with the map2system(1M) command, if the
     old procedure for global user administration (GLOBALPW=yes or auto in
     /etc/default/inet) has been selected. map2system is invoked in turn
     with cron jobs, which are created with ypinit(1M) when NIS is set up.

WARNING
     ypmixer must not be called on a system, on which the new procedure for
     global user administration has been selected.

FILES
     /etc/passwd
     /etc/opasswd
     /etc/shadow
     /etc/oshadow
     /etc/group
     /etc/ogroup
     /var/yp/suppressrebuild
     /etc/default/inet
