SYNOPSIS

#include < gssapi/gssapi.h>

OM_uint32
gss_inquire_cred( OM_uint32 *minor_status, const gss_cred_id_t cred_handle, gss_ctx_id_t *context_handle, gss_name_t *name, OM_uint32 *lifetime, gss_cred_usage_t *cred_usage, gss_OID_set *mechanisms);

DESCRIPTION

Obtains 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 principal.

name

The name whose identity the credential asserts. Storage associated with this name should be freed by the application after use with a call to gss_release_name(). Specify NULL if not required.

lifetime

The number of seconds for which the credential will remain valid. If the credential has expired, this parameter will be set to zero. If the implementation does not support credential expiration, the value GSS_C_INDEFINITE will be returned. Specify NULL if not required.

cred_usage

How the credential may be used. One of the following:

• GSS_C_INITIATE
• GSS_C_ACCEPT
• GSS_C_BOTH

Specify NULL if not required.

mechanisms

Set of mechanisms supported by the credential. Storage associated with this OID set must be freed by the application after use with a call to gss_release_oid_set(). 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
