GSS_INQUIRE_CRED_BY_MECH(3) Programmer's Manual GSS_INQUIRE_CRED_BY_MECH(3)
NAME
gss_inquire_cred_by_mech -- Obtain per-mechanism information about a credential
SYNOPSIS
#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
Obtains per-mechanism information about a credential.
PARAMETERS
minor_status 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 prin-
cipal.
mech_type The mechanism for which information should be returned.
name The name whose identity the credential asserts. Storage associated with this name must be freed by the application after
use with a call to gss_release_name(). Specify NULL if not required.
initiator_lifetime The number of seconds for which the credential will remain 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 zero. If the implementation does not support expiration of initiator cre-
dentials, the value GSS_C_INDEFINITE will be returned. Specify NULL if not required.
acceptor_lifetime The number of seconds for which the credential will remain 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 zero. If the implementation does not support expiration of acceptor cre-
dentials, the value GSS_C_INDEFINITE will be returned. Specify NULL if not required.
cred_usage How the credential may be used with the specified mechanism. One of the following:
GSS_C_INITIATE
GSS_C_ACCEPT
GSS_C_BOTH
Specify NULL if not required.
RETURN VALUES
GSS_S_COMPLETE Successful completion
GSS_S_NO_CRED The referenced credentials could not be accessed
GSS_S_DEFECTIVE_CREDENTIAL The referenced credentials were invalid
GSS_S_CREDENTIALS_EXPIRED The referenced credentials have expired. If the lifetime parameter was not passed as NULL, it will be set to 0.
