Hi to all, I'm new to Freeradius, but not new to OpenLDAP. I got Freeradius running with ldap-connection and Kerberos-authentication for searching the LDAP-tree. Authentication with radtest and a LDAP-user is working: ------------ radtest u1-verw geheim 192.168.56.47 1812 Passw0rd Sent Access-Request Id 23 from 0.0.0.0:50791 to 192.168.56.47:1812 length 77 User-Name = "u1-verw" User-Password = "geheim" NAS-IP-Address = 192.168.56.47 NAS-Port = 1812 Message-Authenticator = 0x00 Cleartext-Password = "geheim" Received Access-Accept Id 23 from 192.168.56.47:1812 to 192.168.56.47:50791 length 20 ------------ I don't want to use MySQL, instead I would like to use OpenLDAP Starting with OpenLDAP 2.5 you can create and manage user and host certificats with the overlay "autoca". You can copy your own CA and the key into OpenLDAP and then let OpenLDAP create the certificate and the key for users and hosts. The certificate will be stored in the attribute userCertificate;binary and userPrivateKey;binary the certificate is in DER-format. I now would like to use the certificates from OpenLDAP for authentication. How can I use certificates located in OpenLDAP for user- and host- authentication? Stefan
