NAME

       nisopaccess - NIS+ operation access control administration command

SYNOPSIS

       nisopaccess [-v] directory operation rights

       nisopaccess [-v] [-r] directory operation

       nisopaccess [-v] [-l] directory [operation]

DESCRIPTION

       Most  NIS+  operations  have  implied access control through the permissions on the objects that they manipulate. For example,  in order to
       read an entry in a table, you must have read permission on that entry. However, some NIS+ operations by default perform no access  checking
       at all and are allowed to all:

       Operation	       Example of commands that use the operation

       NIS_CHECKPOINT	       nisping -C

       NIS_CPTIME	       nisping, rpc.nisd

       NIS_MKDIR	       nismkdir

       NIS_PING 	       nisping,  rpc.nisd

       NIS_RMDIR	       nisrmdir

       NIS_SERVSTATE	       nisbackup,   nisrestore

       NIS_STATUS	       nisstat, rpc.nispasswdd

       The nisopaccess command can be used to enforce access control on these operations on a per NIS+ directory basis.

       The  directory  argument should be the fully qualified name, including the trailing dot, of the NIS+ directory to which nisopaccess will be
       applied. As a short-hand method, if the directory name does not end in a trailing dot, for example  "org_dir",  then  the  domain  name	is
       appended. The domain name is also appended to partial paths such as "org_dir.xyz".

       You  can use upper or lower case for the operation argument. However, you cannot mix cases. The "NIS_"  prefix may be omitted. For example,
       NIS_PING can be specified as  NIS_PING, nis_ping, PING, or ping.

       The rights argument is specified in the format defined by the nischmod(1) command. Since only the read ("r") rights are used to	 determine
       who has the right to perform the operation,  the modify and delete rights may be used to control who can change	access to the operation.

       The  access  checking performed for each operation is as  follows. When an operation requires  access be checked on all	directories served
       by its rpc.nisd(1M), access is denied if even one of the directories prohibits the operation.

       NIS_CHECKPOINT	       Check specified directory, or all directories if there is no directory argument, as is the case when NIS_CHECKPOINT
			       is issued by the "nisping -Ca" command. Return NIS_PERMISSION when access is denied.

       NIS_CPTIME	       Check specified directory. It returns 0 when access  is denied.

       NIS_MKDIR	       Check parent of specified directory. Returns  NIS_PERMISSION when access is denied.

			       If  the parent directory is not available locally, that is, it is not served by this rpc.nisd(1M), NIS_MKDIR access
			       is allowed, though the operation will be executed only if this rpc.nisd is a known replica of the directory.

			       You should note that the NIS_MKDIR operation does not create  a NIS+ directory; it adds a directory to the  serving
			       list for this rpc.nisd, if appropriate.

       NIS_PING 	       Check specified directory. No return value.

       NIS_RMDIR	       Check specified directory. NIS_PERMISSION is returned when access denied.

			       The  NIS_RMDIR  operation does not remove a NIS+ directory; it deletes the directory from the serving list for this
			       rpc.nisd, if appropriate.

       NIS_SERVSTATE	       Check access on all directories served by this rpc.nisd. If access is denied for a tag,	"<permission  denied>"	is
			       returned instead of the tag value.

       NIS_STATUS	       Same as for NIS_SERVSTATE.

       Notice  that  older clients may not supply authentication information for some of the operations listed above. These clients are treated as
       "nobody" when access checking is performed.

       The access control is implemented by creating a NIS+ table  called "proto_op_access" in each NIS+ directory to which  access control should
       be  applied.  The table can be manipulated using normal NIS+ commands. However, nisopaccess is the only supported interface for NIS+ opera-
       tion access control.

OPTIONS

       The following options are supported:

       -l	List the access control for a single operation, or for all operations that have access control enabled.

       -r	Remove access control for a certain operation on the  specified directory.

       -v	Verbose mode.

EXAMPLES

       Example 1: Enabling  Access Control for the NIS_PING Operation

       To enable access control for the NIS_PING operation on "org_dir.`domainname`." such that only the owner of  the	directory  can	perform  a
       NIS_PING, or change the NIS_PING rights:

       example% nisopaccess org_dir NIS_PING o=rmcd,g=,w=,n=

       Example 2: Listing the Access to NIS_PING

       To list the access to the NIS_PING operation for org_dir:

       example% nisopaccess -l org_dir NIS_PING

       NIS_PING    ----rmcd--------    owner.dom.ain.  group.dom.ain.

       Example 3: Removing Access Control for NIS_PING

       To remove access control for NIS_PING on org_dir:

       example% nisopaccess -r org_dir NIS_PING

EXIT STATUS

       The following exit values are returned:

       0	       Successful operation.

       other	       Operation failed. The status is usually the return status from a NIS+ command such as nistbladm.

NOTES

       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 http://www.sun.com/directory/nisplus/transition.html.
