Besides QOPs and security mechanisms, OIDs are also used to indicate
name types, which indicate the format for an associated name. For example,
the function gss_import_name(), which converts the name
of a principal from a string to a gss_name_t type,
takes as one argument the format of the string to be converted. If the name
type is, for example,
GSS_C_NT_HOSTBASED_SERVICE, then the function
knows that the name being input is of the form service@host.
If the name type is
GSS_C_NT_EXPORT_NAME, then the function expects
a GSS-API exported name. Applications can find out which name types are available
for a given mechanism with the gss_inquire_names_for_mech() function.
A list of name types used by GSS-API is provided in Name Types.
