+in this case it is permissible for an implementation to indicate all +mechanisms with which the credential element may be used. +If +.Fa desired_mechs +is an empty set, behavior is undefined. +.Pp +This routine is expected to be used primarily by context acceptors, +since implementations are likely to provide mechanism-specific ways +of obtaining GSS-API initiator credentials from the system login +process. +Some implementations may therefore not support the acquisition of +.Dv GSS_C_INITIATE +or +.Dv GSS_C_BOTH +credentials via +.Fn gss_acquire_cred +for any name other than +.Dv GSS_C_NO_NAME , +or a name produced by applying either +.Fn gss_inquire_cred +to a valid credential, or +.Fn gss_inquire_context +to an active context. +.Pp +If credential acquisition is time-consuming for a mechanism, +the mechanism may choose to delay the actual acquisition until the +credential is required +(e.g. by +.Fn gss_init_sec_context +or +.Fn gss_accept_sec_context ). +Such mechanism-specific implementation +decisions should be invisible to the calling application; +thus a call of +.Fn gss_inquire_cred +immediately following the call of +.Fn gss_acquire_cred +must return valid credential data, +and may therefore incur the overhead of a deferred credential acquisition. +.Sh PARAMETERS +.Bl -tag +.It desired_name +Name of principal whose credential should be acquired. +.It time_req +Number of seconds that credentials should remain valid. +Specify +.Dv GSS_C_INDEFINITE +to request that the credentials have the maximum +permitted lifetime. +.It desired_mechs +Set of underlying security mechanisms that may be used. +.Dv GSS_C_NO_OID_SET +may be used to obtain an implementation-specific default. +.It cred_usage +.Bl -tag -width "GSS_C_INITIATE" +.It GSS_C_BOTH +Credentials may be used either to initiate or accept security +contexts. +.It GSS_C_INITIATE +Credentials will only be used to initiate security contexts. +.It GSS_C_ACCEPT +Credentials will only be used to accept security contexts. +.El +.It output_cred_handle +The returned credential handle. +Resources +associated with this credential handle must be released by +the application after use with a call to +.Fn gss_release_cred . +.It actual_mechs +The set of mechanisms for which the credential is valid. +Storage associated with the returned OID-set must be released by the +application after use with a call to +.Fn gss_release_oid_set . +Specify +.Dv NULL if not required. +.It time_rec +Actual number of seconds for which the returned credentials will +remain valid. +If the implementation does not support expiration of credentials, +the value +.Dv GSS_C_INDEFINITE +will be returned. +Specify NULL if not required. +.It minor_status +Mechanism specific status code. +.El +.Sh RETURN VALUES +.Bl -tag +.It GSS_S_COMPLETE +Successful completion. +.It GSS_S_BAD_MECH +Unavailable mechanism requested. +.It GSS_S_BAD_NAMETYPE +Type contained within desired_name parameter is not supported. +.It GSS_S_BAD_NAME +Value supplied for desired_name parameter is ill formed. +.It GSS_S_CREDENTIALS_EXPIRED +The credentials could not be acquired Because they have expired. +.It GSS_S_NO_CRED +No credentials were found for the specified name. +.El +.Sh SEE ALSO +.Xr gss_init_sec_context 3 , +.Xr gss_accept_sec_context 3 , +.Xr gss_inquire_cred 3 , +.Xr gss_inquire_context 3 , +.Xr gss_release_cred 3 , +.Xr gss_release_oid_set 3 +.Sh STANDARDS +.Bl -tag +.It RFC 2743 +Generic Security Service Application Program Interface Version 2, Update 1 +.It RFC 2744 +Generic Security Service API Version 2 : C-bindings +.\" .Sh HISTORY +.El +.Sh HISTORY +The +.Nm +manual page example first appeared in +.Fx 7.0 . +.Sh AUTHORS +John Wray, Iris Associates |
