How To Determine What Netgroups A User Belongs To

[RobSandifer]

Greetings,

In an NIS environment, what command given at the CLI
will allow me to view/determine any/all netgroups that a
user belongs to?

I am running HP-UX ver. 11.11 in a large NIS environment.

Note: I heard that the following command would provide
the names of any/all netgroup that user "smith" belongs to.
Unfortunately, it did not work. All helpful comments are
welcomed and appreciated.

# ypmatch 'smith.*' netgroup.byuser
ypmatch: can't match smith.*.
Reason: no such key in map



Thanks ahead of time!
