When you create an NIS+ object, NIS+ assigns that object
a default set of access rights for the owner and group classes. By default,
the owner is the NIS+ principal who creates the object. The default group
is the group named in the NIS_GROUP
environment variable.
NIS+ provides two different ways to change the default rights that are automatically assigned to an NIS+ object when it is created.
The NIS_DEFAULTS
environment variable. NIS_DEFAULTS
stores a set of security-related default values, one of which is access rights.
These default access rights are the ones automatically assigned to an object
when it is created. (See Displaying NIS+ Defaults—The nisdefaults Command for details.)
If the value of the NIS_DEFAULTS
environment variable is changed, objects created after the change are assigned
the new values. However, previously created objects are not affected.
The -D option, which is available with several
NIS+ commands. When you use the -D option as part of the command
to create an NIS+ object, it overrides the default rights specified by the NIS_DEFAULTS
environment variable and allows
you to explicitly specify an initial set of rights for that object. (See Specifying Nondefault Security Values at Creation Time for details.)
When an NIS+ object is created, it comes into existence
with a default set of access rights (from either the NIS_DEFAULTS
environment variable or as specified with the -D option). These default rights can be changed with the
