krb5_ccache_intro − The credential cache functions
krb5_ccache structure holds a Kerberos credential cache.
Heimdal support the follow types of credential caches:
• |
SCC Store the credential in a database |
|||
• |
FILE Store the credential in memory |
|||
• |
MEMORY Store the credential in memory |
|||
• |
API A credential cache server based solution for Mac OS X |
|||
• |
KCM A credential cache server based solution for all platforms |
This is a minimalistic version of klist:
#include <krb5.h>
int
main (int argc, char **argv)
{
krb5_context context;
krb5_cc_cursor cursor;
krb5_error_code ret;
krb5_ccache id;
krb5_creds creds;
if
(krb5_init_context (&context) != 0)
errx(1, "krb5_context");
ret =
krb5_cc_default (context, &id);
if (ret)
krb5_err(context, 1, ret, "krb5_cc_default");
ret =
krb5_cc_start_seq_get(context, id, &cursor);
if (ret)
krb5_err(context, 1, ret,
"krb5_cc_start_seq_get");
while((ret =
krb5_cc_next_cred(context, id, &cursor, &creds)) ==
0){
char *principal;
krb5_unparse_name(context,
creds.server, &principal);
printf("principal: %s\n", principal);
free(principal);
krb5_free_cred_contents (context, &creds);
}
ret = krb5_cc_end_seq_get(context, id, &cursor);
if (ret)
krb5_err(context, 1, ret,
"krb5_cc_end_seq_get");
krb5_cc_close(context, id);
krb5_free_context(context);
return 0;
