SYNOPSIS

krb5_error_code
krb5_get_credentials(krb5_context context, krb5_flags options, krb5_ccache ccache, krb5_creds *in_creds, krb5_creds **out_creds);

krb5_error_code
krb5_get_credentials_with_flags(krb5_context context, krb5_flags options, krb5_kdc_flags flags, krb5_ccache ccache, krb5_creds *in_creds, krb5_creds **out_creds);

krb5_error_code
krb5_get_kdc_cred(krb5_context context, krb5_ccache id, krb5_kdc_flags flags, krb5_addresses *addresses, Ticket *second_ticket, krb5_creds *in_creds, krb5_creds **out_creds);

krb5_error_code
krb5_get_renewed_creds(krb5_context context, krb5_creds *creds, krb5_const_principal client, krb5_ccache ccache, const char *in_tkt_service);

DESCRIPTION

Valid flags to pass into options argument are:

KRB5_GC_CACHED

Only check the ccache, don't got out on network to fetch credential.

KRB5_GC_USER_USER

Request a user to user ticket. This option doesn't store the resulting user to user credential in the ccache.

KRB5_GC_EXPIRED_OK

returns the credential even if it is expired, default behavior is trying to refetch the credential from the KDC.

Flags are KDCOptions, note the caller must fill in the bit-field and not use the integer associated structure.

krb5_get_credentials() works the same way as krb5_get_credentials_with_flags() except that the flags field is missing.

krb5_get_kdc_cred() does the same as the functions above, but the caller must fill in all the information andits closer to the wire protocol.

krb5_get_renewed_creds() renews a credential given by in_tkt_service (if NULL the default krbtgt) using the credential cache ccache. The result is stored in creds and should be freed using krb5_free_creds.

EXAMPLES

#include <krb5.h>

int
getcred(krb5_context context, krb5_ccache id, krb5_creds **creds)
{
    krb5_error_code ret;
    krb5_creds in;

    ret = krb5_parse_name(context, "client@EXAMPLE.COM",
			  &in.client);
    if (ret)
	krb5_err(context, 1, ret, "krb5_parse_name");

    ret = krb5_parse_name(context, "host/server.example.com@EXAMPLE.COM",
			  &in.server);
    if (ret)
	krb5_err(context, 1, ret, "krb5_parse_name");

    ret = krb5_get_credentials(context, 0, id, &in, creds);
    if (ret)
	krb5_err(context, 1, ret, "krb5_get_credentials");

    return 0;
}
