The IPA server uses TLSv1.0 and includes medium encryption ciphers

Solution Unverified - Updated -

Issue

  • Our sercurity checked the ldaps / https connection on our (almost default-out-of-the-box) IPA server.

    • For HTTPS:

      • Turn off TLSv1.0 (against BEAST);
      • Turn off Medium grade encryption;
      • Turn off 3DES and RC4;
      • PFS is not offered while this cipher-wise would be possible;
      • Secure Client-Initiated Renegotiation does not work.

    • For LDAPs:

      • Turn off TLSv1.0 (against BEAST);
      • Turn off Medium grade encryption;
      • Secure Client-Initiated Renegotiation does not work.

Environment

  • Red Hat Enterprise Linux (RHEL) 7.2
  • ipa-server-4.2.0
