28 * Test program for gss_export_name, intended to be run from a Python test
29 * script. Imports a name, canonicalizes it to a mech, exports it,
30 * re-imports/exports it to compare results, and then prints the hex form of
31 * the exported name followed by a newline.
32 *
33 * Usage: ./t_export_name [-k|-s] user:username|krb5:princ|host:service@host
34 *
35 * The name is imported as a username, krb5 principal, or hostbased name.
36 * By default or with -k, the name is canonicalized to the krb5 mech; -s
37 * indicates SPNEGO instead.
