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: o SCC Store the credential in a database o FILE Store the credential in memory o MEMORY Store the credential in memory o API A credential cache server based solution for Mac OS X o 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 1.5.2 11 Jan 2012 krb5_ccache_intro(3)
