I understand. But what I am asking is what code can be in pam_krb5 to
tell your libraries to load a plugin?  The Heimdal code adds
one extra routine, krb5_get_init_creds_opt_set_pkinit. With the MIT code
if the plugin was not available a routine like this could return an error.

OK, then generalize by having a krb5_get_init_creds_opt_set_plugin,
instead, and pass it character string parameters, that could have been
passed as options to pam_krb5 or found in krb5.conf.
