We have an 802.11 service that uses a captive portal (Vernier) system authenticating via RADIUS to kerberos. Currently there's no authorization, except implicitly (i.e. presence of an entry in our kerberos database). We want to start doing authorization using the campus LDAP directory. I'm trying to set this up with rlm_ldap on freeradius 1.0.5, but I'm having trouble getting it to work. The LDAP server doesn't have any of the RADIUS attributes in its schema, so I'll have to come up with a custom mapping, but that's not the problem (yet). Rather, I can't get rlm_ldap to make an encrypted connection to the LDAP server. Here's the start of the ldap section in the modules {} part of radiusd.conf: ldap airbears-ldap { server = "ldaps://our.ldap.server" identity = password = basedn = "ou=people,dc=berkeley, dc=edu" filter = "(uid=%{Stripped-User-Name:-%{User-Name}})" ldap_debug = -1 tls_cacertfile = ${confdir}/certs/ourcertfile.crt tls_require_cert = "never" ... } Everything else in the ldap section is still the default. (That'll have to change, but I want to get the connection working first). The above should set up an anonymous bind over an encrypted connection, but it fails with "TLS: can't connect". (See attached debug snippet). However, if I change the 'ldaps:' to 'ldap:', the ldap query works. I've tried various combinations of 'port' (in the ldap section), 'start_tls' and 'tls_mode' but any combination that specifies a TLS connection fails. I don't think there's a problem with our openldap or openssl libraries, because I can do the same query (from the same system) with 'ldapsearch' without any problems. The RADIUS server is running FreeBSD 5.4-STABLE, using openssl 0.9.8a, and openldap 2.2.29, both built from ports. (The freeradius is also built from ports). Any ideas on what the problem might be, or where I might look next? Thanks, -- George C.
