NAME

       nisupdkeys - update the public keys in a NIS+ directory object

SYNOPSIS

       /usr/lib/nis/nisupdkeys [-a | -C] [-H host] [directory]

       /usr/lib/nis/nisupdkeys -s [-a | -C] -H host

DESCRIPTION

       This  command updates the public keys in an NIS+ directory object. When the public key(s) for a NIS+ server are changed, nisupdkeys reads a
       directory object and attempts to get the public key data for each server of that directory. These keys are placed in the  directory  object
       and  the object is then modified to reflect the new keys. If directory is present, the directory object for that directory is updated. Oth-
       erwise the directory object for the default domain is updated. The new key must be propagated to all directory objects that reference  that
       server.

       On  the	other hand, nisupdkeys -s gets a list of all the directories served by host and updates those directory objects. This assumes that
       the caller has adequate permission to change all the associated directory objects. The list of directories being served by a  given  server
       can  also  be  obtained	by nisstat(1M). Before you do this operation, make sure that the new address/public key has been propagated to all
       replicas. If multiple authentication mechanisms are configured using nisauthconf(1M), then the keys  for  those	mechanisms  will  also	be
       updated or cleared.

       The  user  executing  this  command must have modify access to the directory object for it to succeed. The existing directory object can be
       displayed with the niscat(1) command using the -o option.

       This command does not update the directory objects stored in the NIS_COLD_START file on the NIS+ clients.

       If a server is also the root master server, then nisupdkeys -s cannot be used to update the root directory.

OPTIONS

       -a	  Update the universal addresses of the NIS+ servers in the directory object. Currently, this only works for the TCP/IP family	of
		  transports.  This option should be used when the IP address of the server is changed. The server's new address is resolved using
		  getipnodebyname(3SOCKET) on this machine. The /etc/nsswitch.conf file must point to the correct source for ipnodes and hosts for
		  this resolution to work.

       -C	  Specify  to  clear rather than set the public key(s). Communication with a server that has no public key(s) does not require the
		  use of secure RPC.

       -H host	  Limit key changes only to the server named host. If the hostname is not a fully qualified NIS+ name, then it is assumed to be  a
		  host in the default domain. If the named host does not serve the directory, no action is taken.

       -s	  Update all the NIS+ directory objects served by the specified server. This assumes that the caller has adequate access rights to
		  change all the associated directory objects. If the NIS+ principal making this call does not have adequate permissions to update
		  the directory objects, those particular updates will fail and the caller will be notified. If the rpc.nisd on host cannot return
		  the list of servers it serves, the command will print an error message. The caller would then have to invoke nisupdkeys multiple
		  times (as in the first synopsis), once per NIS+ directory that it serves.

EXAMPLES

       Example 1 Using nisupdkeys

       The following example updates the keys for servers of the foo.bar. domain.

	 example% nisupdkeys foo.bar.

       This example updates the key(s) for host fred that serves the foo.bar. domain.

	 example% nisupdkeys -H fred foo.bar.

       This example clears the public key(s) for host wilma in the foo.bar. directory.

	 example% nisupdkeys -CH wilma foo.bar.

       This example updates the public key(s) in all directory objects that are served by the host wilma.

	 example% nisupdkeys -s -H wilma

NOTES

       NIS+  might not be supported in future releases of the Solaris Operating system. Tools to aid the migration from NIS+ to LDAP are available
       in the current Solaris release. For more information, visit http://www.sun.com/directory/nisplus/transition.html.
