krb5_ccache_intro(3) Heimdal Kerberos 5 library krb5_ccache_intro(3) NAME krb5_ccache_intro - The credential cache functions Kerberos credential caches 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 Example 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; } Version 7.8.0 Tue Nov 15 2022 krb5_ccache_intro(3)
