Name Types

A name type indicates the format of the associated name. See Names in GSS-API and GSS-API OIDs for more on names and name types. The GSS-API supports the gss_OID name types in the following table.

GSS_C_NO_NAME

The symbolic name GSS_C_NO_NAME is recommended as a parameter value to indicate that no value is supplied in the transfer of names.

GSS_C_NO_OID

This value corresponds to a null input value instead of an actual object identifier. Where specified, the value indicates interpretation of an associated name that is based on a mechanism-specific default printable syntax.

GSS_C_NT_ANONYMOUS

A means to identify anonymous names. This value can be compared with to determine in a mechanism-independent fashion whether a name refers to an anonymous principal.

GSS_C_NT_EXPORT_NAME

A name that has been exported with the gss_export_name() function.

GSS_C_NT_HOSTBASED_SERVICE

Used to represent services that are associated with host computers. This name form is constructed using two elements, service and hostname, as follows: service@hostname.

GSS_C_NT_MACHINE_UID_NAME

Used to indicate a numeric user identifier corresponding to a user on a local system. The interpretation of this value is OS-specific. The gss_import_name() function resolves this UID into a user name, which is then treated as the User Name Form.

GSS_C_NT_STRING_STRING_UID_NAME

Used to indicate a string of digits that represents the numeric user identifier of a user on a local system. The interpretation of this value is OS-specific. This name type is similar to the Machine UID Form, except that the buffer contains a string that represents the user ID.

GSS_C_NT_USER_NAME

A named user on a local system. The interpretation of this value is OS-specific. The value takes the form: username.
