Hi everybody, I'm having some problems with freeradius and ldap authentication. I need to authenticate an user connecting in vpn to my pptpd daemon, which will ask permission to freeradius. I installed freeradius and configured it to use ldap in this way (i stripped comments to shorten the config files): sites-available/default: authorize { ldap preprocess chap mschap digest suffix eap { ok = return } expiration logintime pap } authenticate { Auth-Type PAP { pap } Auth-Type CHAP { chap } Auth-Type MS-CHAP { mschap } Auth-Type LDAP { ldap } } preacct { preprocess acct_unique suffix files } accounting { detail unix radutmp exec } session { radutmp } post-auth { ldap exec Post-Auth-Type REJECT { attr_filter.access_reject } } pre-proxy { } post-proxy { eap } modules/ldap: ldap { server = "10.1.98.50" identity = "cn=admin,dc=domain,dc=private" password = password basedn = "dc=domain,dc=private" filter = "(uid=%{%{Stripped-User-Name}:-%{User-Name}})" ldap_connections_number = 5 timeout = 4 timelimit = 3 net_timeout = 1 tls { start_tls = no } dictionary_mapping = ${confdir}/ldap.attrmap password_attribute = userPassword edir_account_policy_check = no } radiusd.conf prefix = /usr exec_prefix = /usr sysconfdir = /etc localstatedir = /var sbindir = ${exec_prefix}/sbin logdir = /var/log/freeradius raddbdir = /etc/freeradius radacctdir = ${logdir}/radacct name = freeradius confdir = ${raddbdir} run_dir = ${localstatedir}/run/${name} db_dir = ${raddbdir} libdir = /usr/lib/freeradius pidfile = ${run_dir}/${name}.pid user = freerad group = freerad max_request_time = 30 cleanup_delay = 5 max_requests = 1024 listen { type = auth ipaddr = * port = 0 } listen { ipaddr = * port = 0 type = acct } hostname_lookups = no allow_core_dumps = no regular_expressions = yes extended_expressions = yes log { destination = files file = ${logdir}/radius.log syslog_facility = daemon stripped_names = no auth = no auth_badpass = no auth_goodpass = no } checkrad = ${sbindir}/checkrad security { max_attributes = 200 reject_delay = 1 status_server = yes } proxy_requests = yes $INCLUDE proxy.conf $INCLUDE clients.conf thread pool { start_servers = 5 max_servers = 32 min_spare_servers = 3 max_spare_servers = 10 max_requests_per_server = 0 } modules { $INCLUDE ${confdir}/modules/ $INCLUDE eap.conf } instantiate { exec expr expiration logintime } $INCLUDE policy.conf $INCLUDE sites-enabled/ When I run freeradius -X this is what I get: FreeRADIUS Version 2.1.10, for host x86_64-pc-linux-gnu, built on Sep 24 2012 at 17:58:57 Copyright (C) 1999-2009 The FreeRADIUS server project and contributors.
