+ *  The input name may multiple name, or generic name types.
+ *
+ *  If the input_name if of the GSS_C_NT_USER_NAME, and the Kerberos
+ *  mechanism is specified, the resulting MN type is a
+ *  GSS_KRB5_NT_PRINCIPAL_NAME.
+ *
+ *  For more information about @ref internalVSmechname.
+ *
+ *  @param minor_status minor status code.
+ *  @param input_name name to covert, unchanged by gss_canonicalize_name().
+ *  @param mech_type the type to convert Name too.
+ *  @param output_name the resulting type, release with
+ *         gss_release_name(), independent of input_name.
+ *
+ *  @returns a gss_error code, see gss_display_status() about printing
+ *         the error code.
