How to configure FreeRADIUS authentication in FIPS mode

Solution Verified - Updated -

Issue

  • How to configure FreeRadius authentication in FIPS mode for IPA users using the ldap module in FreeRADIUS.
  • How to configure FreeRadius authentication in FIPS mode for local users using the/etc/raddb/users configuration file.

NOTE(1): You can use the same set of steps to configure FreeRADIUS authentication in default non-FIPS mode, except that you can skip step 1.

NOTE(2): Though FreeRADIUS can run in FIPS mode, it does not mean that it is FIPS compliant as it uses weak ciphers and functions when in FIPS mode.

Environment

  • FIPS mode enabled - running IPA server in FIPS mode is supported from >= RHEL 7.4.
  • freeradius-3.0.20-7
  • IPA server 4.9.x
  • krb5-server-1.18.2-7
