Hello I install freeradius on Debian Sarge machine. I have my user in ldap and I use that directory to auth. them. It's works. But when I want to use TLS in connections between radius and ldap, I have that error in radius log. rlm_ldap: ldap_get_conn: Checking Id: 0 rlm_ldap: ldap_get_conn: Got Id: 0 rlm_ldap: attempting LDAP reconnection rlm_ldap: (re)connect to ldap:636, authentication 0 rlm_ldap: setting TLS mode to 1 rlm_ldap: setting TLS CACert File to /etc/freeradius/cert/ca.crt rlm_ldap: setting TLS CACert File to /etc/freeradius/cert/ rlm_ldap: setting TLS Require Cert to never rlm_ldap: setting TLS Cert File to /etc/freeradius/cert/radius.crt rlm_ldap: setting TLS Key File to /etc/freeradius/cert/radius.key rlm_ldap: starting TLS rlm_ldap: ldap_start_tls_s() rlm_ldap: could not start TLS Can't contact LDAP server rlm_ldap: (re)connection attempt failed rlm_ldap: search failed rlm_ldap: ldap_release_conn: Release Id: 0 When i saw that error, i check ldap logs. My ldap is configure with SSL not a TLS. Now i have a problem with configure freeradius to work with SSL ldap not TLS ldap :( I have in radiusd.conf: server = "ldap" port = 636 #port = 389 ... filter = "(uid=%u)" base_filter = "(objectclass=radiusprofile)" start_tls = no # tls_cacertfile = /path/to/cacert.pem tls_cacertfile = /etc/freeradius/cert/ca.crt # tls_cacertdir = /path/to/ca/dir/ tls_cacertdir = /etc/freeradius/cert/ tls_cacertdir = /etc/freeradius/cert/ # tls_certfile = /path/to/radius.crt tls_certfile = /etc/freeradius/cert/radius.crt # tls_keyfile = /path/to/radius.key tls_keyfile = /etc/freeradius/cert/radius.key #tls_mode = yes I read about SSL in freeradius and i thought that that conf. use SSL to connections with ldap, but i wrong ? Can somebody tell me how i can use SSL auth between ldap and freeradius ? BR. Kamyk
