NAME

gss_inquire_cred_by_mech - obtain per-mechanism information about a credential

SYNOPSIS

cc -flag ... file ...-lgss [library ...] #include <gssapi/gssapi.h> OM_uint32 gss_inquire_cred_by_mech(OM_uint32 *minor_status, const gss_cred_id_t cred_handle, const gss_OID mech_type, gss_name_t *name, OM_uint32 *initiator_lifetime, OM_uint32 *acceptor_lifetime, gss_cred_usage_t *cred_usage);

DESCRIPTION

The gss_inquire_cred_by_mech() obtains per-mechanism information about a credential.

PARAMETERS

The parameter descriptions for gss_inquire_cred_by_mech() follow:

minor_status: A mechanism specific status code.
cred_handle: A handle that refers to the target credential. Specify GSS_C_NO_CREDENTIAL to inquire about the default initiator principal.
mech_type: The mechanism for which the information should be returned.
name: The name whose identity the credential asserts. Any storage associated with this name must be freed by the application after use by a call to gss_release_name(3GSS).
initiator_lifetime: The number of seconds that the credential is capable of initiating security contexts under the specified mechanism. If the credential can no longer be used to initiate contexts, or if the credential usage for this mechanism is GSS_C_ACCEPT, this parameter will be set to 0. Specify NULL if this parameter is not required.
acceptor_lifetime: The number of seconds that the credential is capable of accepting security contexts under the specified mechanism. If the credential can no longer be used to accept contexts, or if the credential usage for this mechanism is GSS_C_INITIATE, this parameter will be set to 0. Specify NULL if this parameter is not required.
cred_usage: How the credential may be used with the specified mechanism. The cred_usage parameter may contain one of the following values: GSS_C_INITIATE, GSS_C_ACCEPT, or GSS_C_BOTH. Specify NULL if this parameter is not required.

RETURN VALUES

gss_inquire_cred_by_mech() may return the following status codes:

GSS_S_COMPLETE: Successful completion.
GSS_S_NO_CRED: The referenced credentials cannot be accessed.
GSS_S_DEFECTIVE_CREDENTIAL: The referenced credentials are invalid..
GSS_S_CREDENTIALS_EXPIRED: The credentials cannot be added because they have expired.
GSS_S_FAILURE: The underlying mechanism detected an error for which no specific GSS status code is defined. The mechanism-specific status code reported by means of the minor_status parameter details the error condition.
