34 *  gss_canonicalize_name takes a Internal Name (IN) and converts in into a

36 *
37 *  The input name may multiple name, or generic name types.
38 *
39 *  If the input_name if of the GSS_C_NT_USER_NAME, and the Kerberos
40 *  mechanism is specified, the resulting MN type is a
41 *  GSS_KRB5_NT_PRINCIPAL_NAME.
42 *
43 *  For more information about @ref internalVSmechname.
44 *
45 *  @param minor_status minor status code.
46 *  @param input_name name to covert, unchanged by gss_canonicalize_name().
47 *  @param mech_type the type to convert Name too.
48 *  @param output_name the resulting type, release with
49 *         gss_release_name(), independent of input_name.
50 *
51 *  @returns a gss_error code, see gss_display_status() about printing
52 *         the error code.
