28 * Test program for krb5_gss_import_cred, intended to be run from a Python test
29 * script. Creates an initiator credential for the default ccache and an
30 * acceptor principal for the default keytab (possibly using a specified keytab
31 * principal), and performs a one-token context exchange using a specified
32 * target principal. If the exchange is successful, queries the context for
33 * the acceptor name and prints it. If any call is unsuccessful, displays an
34 * error message. Exits with status 0 if all operations are successful, or 1
35 * if not.
36 *
37 * Usage: ./t_imp_cred target-princ [keytab-princ]
