I would like to know if it's possible to have more then one authenticaton backend with Freeradius.
Zes.
Let's say I have User1 on OpenLDAP and User2 On Microosft Windows Active Directory.
No problem.
I configure my device to send Authentication request (Radius) to Freeradius User1 and User2 should be able to authentice.
I was able to make it work separetly but not both at the same time
If you were using ldap as authentication oracle, your problems have nothing to do with where you stored data but with authentication protocol. Ldap won't work with mschap requests (that's clearly stated in ldap module configuration file) while AD integration (ntlm_auth) is configured in mschap module and won't work with pap requests. If you use ldap only as storage (don't set auth type) it will work with mschap requests. If you don't remove ntlm_auth from authenticate section (AD integration documentation suggests that you should) pap will work with AD. Ivan Kalik Kalik Informatika ISP
