/* There are two (or more) NSS test modules named nss_test1,
nss_test2, etc. Each one will call a function IN THE TEST CASE
called _nss_test1_init_hook(test_tables *) (or _nss_test2_*, etc).
In your copy of the hook function, you may change the *_table
pointers in the passed struct to point to static tables in your
test case, and the test modules will use that table instead.
Your tables MUST end with an entry that has a *_LAST() macro.
Use the *_ISLAST() macro to test for end of list.

configure NSS to use the test modules. */
