nisln - symbolically link NIS+ objects


     nisln [-L] [-D defaults] name linkname


     The nisln command links a NIS+ object named name to  a  NIS+
     name linkname. If name is an indexed name (see nismatch(1)),
     the link points to entries  within  a  NIS+  table.  Clients
     wishing  to  look up information in the name service can use
     the FOLLOW_LINKS flag to force the client library to  follow
     links  to  the  name they point to. Further, all of the NIS+
     administration commands accept the -L switch indicating they
     should  follow  links (see nis_names(3NSL) for a description
     of the FOLLOW_LINKS flag).

     When creating the  link,  nisln  verifies  that  the  linked
     object  exists.  Once  created,  the  linked  object  may be
     deleted or replaced and the link will not  be  affected.  At
     that time, the link will become invalid and attempts to fol-
     low it will return  NIS_LINKNAMEERROR to  the  client.  When
     the  path  attribute  in tables specifies a link rather than
     another table,  the  link  will  be  followed  if  the  flag
     FOLLOW_LINKS  was  present  in  the call to  nis_list() (see
     nis_tables(3NSL)) and ignored if the flag is not present. If
     the flag is present and the link is no longer valid, a warn-
     ing is sent to the system logger and the link is ignored.


     The following options are supported:

     -D defaults
           Specify a different set of defaults to be used for the
           creation  of the link object. The defaults string is a
           series of tokens separated  by  colons.  These  tokens
           represent  the  default values to be used for the gen-
           eric object properties. All of the  legal  tokens  are
           described below.

                 This token sets the default  time  to  live  for
                 objects  that  are  created by this command. The
                 value time is specified in the format as defined
                 by  the  nischttl(1)  command. The default is 12

                 This token specifies  that  the  NIS+  principal
                 ownername  should  own  the  created object. The
                 default for this value is the the principal  who
                 is executing the command.

                 This token specifies that  the  group  groupname
                 should be the group owner for the object that is
                 created. The default is NULL.

                 This token specifies the set  of  access  rights
                 that are to be granted for the given object. The
                 value rights  is  specified  in  the  format  as
                 defined by the  nischmod(1) command. The default
                 value is ----rmcdr---r---.

     -L    When present, this option specifies that this  command
           should  follow  links.  If name is itself a link, then
           this command will follow it to the linked object  that
           it  points  to. The new link will point to that linked
           object rather than to name.


     Example 1: Creating a link

     In this example, we create a link  in  the  domain
     named hosts that points to the object

     example% nisln

     Example 2: Making a link that points  to  an  entry  in  the
     hosts table

     In this example, we make a link that points
     to an entry in the hosts table in

     example% nisln '[name=example],'


           If this variable is set, and  the  NIS+  name  is  not
           fully  qualified,  each  directory  specified  will be
           searched  until  the  object  is  found  (see   nisde-


     The following exit values are returned:

     0     Successful operation.

     1     Operation failed.

     NIS+ might not  be  supported  in  future  releases  of  the
     SolarisTM  Operating Environment. Tools to aid the migration
     from NIS+ to LDAP are available in the Solaris  9  operating
     environment.      For      more      information,      visit
