.It mech_type
|
|
The mechanism for which information should be returned.
|
|
.It name
|
|
The name whose identity the credential asserts.

|
or if the credential usage for this mechanism is
|
|
.Dv GSS_C_ACCEPT ,
|
|
this parameter will be set to zero.
|
|
If the implementation does not support expiration of initiator
|
|
credentials,
