If MSCHAP, MSCHAPv2 or EAP-MSCHAP-V2 support is required, Radiator needs a module that provides support for the MD4 digest. Support for MD4 is provided by Radiator Radius::UtilXS and Digest::MD4. There is no need to install the both modules. You can choose either one.

MD4 support was added in version Radius::UtilXS version 2.0. See Section 2.1.9. Radiator Radius::UtilXS for more information.

If Digest::MD4 is not present in your Perl distribution, see Section 2.1.2. CPAN for how to obtain and install it.
