NAME
      nischmod - change access rights on a NIS+ object
 


SYNOPSIS
      nischmod [ -AfLP ]  mode  name ...
 


DESCRIPTION
      nischmod changes  the  access  rights  (mode)  of  the  NIS+
      objects  or entries specified by  name to mode.  Entries are
      specified using indexed names (see nismatch(1)). Only  prin-
      cipals with modify access to an object may change its mode.
 
      mode has the following form:
 
           rights [, rights]...
 
 
      rights has the form:
 
           [ who ] op permission [ op permission ]...
 
 
      who is a combination of:
 
      n     Nobody's permissions.
 
      o     Owner's permissions.
 
      g     Group's permissions.
 
      w     World's permissions.
 
      a     All, or  owg.
 
            If  who is omitted, the default is  a.
 
      op is one of:
 
      +     To grant the  permission.
 
      -     To revoke the  permission.
 
      =     To set the permissions explicitly.
 
      permission is any combination of:
 
      r     Read.
 
      m     Modify.
 
      c     Create.

OPTIONS
      The following options are supported:
 
      -A    Modify all entries in all tables in the  concatenation
            path that match the search criteria specified in name.
            This option implies the -P switch.
 
      -f    Force the operation and fail silently if it  does  not
            succeed.
 
      -L    Follow links and change the permission of  the  linked
            object  or  entries  rather than the permission of the
            link itself.
 
      -P    Follow the concatenation path within  a  named  table.
            This  option is only applicable when either name is an
            indexed name or the -L switch is  also  specified  and
            the named object is a link pointing to an entry.
 
 EXAMPLES
      Example 1: Examples of the nischmod command.
 
      This example gives everyone read access to an object.  (that
      is, access for owner, group, and all).
 
      example% nischmod a+r object
 
      This example denies create and modify privileges  to   group
      and unauthenticated clients (nobody).
 
      example% nischmod gn-cm object
 
      In this example, a complex set of permissions are set for an
      object.
 
      example% nischmod o=rmcd,g=rm,w=rc,n=r object
 
      This example sets the permissions of an entry in  the  pass-
      word table so that the group owner can modify them.
 
      example% nischmod g+m '[uid=55],passwd.org_dir'
 
      The next example changes the permissions of a linked object.
 
      example% nischmod -L w+mr linkname
 
 ENVIRONMENT VARIABLES
      NIS_PATH
            If this variable is set, and  the  NIS+  name  is  not
            fully  qualified,  each  directory  specified  will be
