I'm working on a project and I need to make the clients authenticate themselves by using 802.1x, I'm using RADIUS as an Authentication Server, my question is what is the best choice as a back-end Database for RADIUS, is it openLDAP or Active Directory?

What is the pros and cons of both implementations?

Thanks in advance

  • mysql, postgres, etc. Unless there's other reasons to setup LDAP, there's no point using RADIUS to relay to LDAP. It's just adding complexity. – Ricky Beam May 12 '14 at 16:37
  • We have big LDAP DB so we have to use LDAP ,, My question is do I have to replace it by AD ,is AD better than LDAP or not? thanks @RickyBeam – Nidal May 12 '14 at 16:41
  • Use what you already have, if it works for you. Also, some systems can auth directly to LDAP. (you haven't said what hardware you're using.) – Ricky Beam May 12 '14 at 18:47
  • This is like asking what routing protocol to use. The right answer is the one you have. Moving from LDAP to AD is non trivial and a bad idea unless you really, really, really have to. – fredpbaker May 13 '14 at 1:04

I have found a useful PDF which answer this question and which explain in details the advantages of openLDAP over Active Directrory
