I am trying to setup Freeradius to authenticate against an active directory server. I do not want it to do a ldapsearch to get authorization. I have looked on the mailing lists but have not found how to do this in my situation. I did read the rlm_ldap manual and am aware of the ldap-UserDN variable. I am unable to get Freeradius to set the bind DN to what I attempt to set the ldap-userdn variable to in the authentication phase. It insists on setting DN to the entire CN. Any clues? Thanks. Here are the relevant files: /etc/raddb/radiusd.conf ***************************************************************************************** prefix = /usr exec_prefix = ${prefix} sysconfdir = /etc localstatedir = /var sbindir = ${exec_prefix}/sbin logdir = ${localstatedir}/log/radius raddbdir = ${sysconfdir}/raddb radacctdir = ${logdir}/radacct confdir = ${raddbdir} run_dir = ${localstatedir}/run/radiusd log_file = ${logdir}/radius.log libdir = /usr/lib64 pidfile = ${run_dir}/radiusd.pid user = radiusd group = radiusd max_request_time = 30 delete_blocked_requests = no cleanup_delay = 5 max_requests = 1024 bind_address = * port = 0 hostname_lookups = no allow_core_dumps = no regular_expressions = yes extended_expressions = yes log_stripped_names = no log_auth = no log_auth_badpass = no log_auth_goodpass = no usercollide = no lower_user = no lower_pass = no nospace_user = no nospace_pass = no checkrad = ${sbindir}/checkrad security { max_attributes = 200 reject_delay = 1 status_server = no } proxy_requests = yes $INCLUDE ${confdir}/proxy.conf $INCLUDE ${confdir}/clients.conf snmp = no $INCLUDE ${confdir}/snmp.conf thread pool { start_servers = 5 max_servers = 32 min_spare_servers = 3 max_spare_servers = 10 max_requests_per_server = 0 } modules { pap { auto_header = yes } chap { authtype = CHAP } pam { pam_auth = radiusd } unix { cache = no cache_reload = 600 radwtmp = ${logdir}/radwtmp } $INCLUDE ${confdir}/eap.conf mschap { } ldap { server = "ldaps://ad-ldap.subdomain.domain.com" port = 636 identity = "username" password = "password" basedn = "ou=North America,dc=subdomain,dc=domain,dc=com" ldap_debug = 0x0028 binddn = "(SamAccountName=%u)" base_filter = "(objectclass=*)" filter = "(SamAccountName=%u)" start_tls = no tls_require_cert = "never" password_radius_attribute = "NT-Password" password_attribute = "userPassword" password_header = "{clear}" #access_attr = "telephoneNumber" dictionary_mapping = ${raddbdir}/ldap.attrmap ldap_connections_number = 5 edir_account_policy_check=no #default_profile = "ladp-userdn" #groupname_attribute = cn #groupmembership_filter = "(|(&(objectClass=GroupOfNames)(member= %{Ldap-UserDn}))(&(objectClass=GroupOfUniqueNames)(uniquemember= %{Ldap-UserDn})))" #groupmembership_attribute = memberOf timeout = 4 timelimit = 3 net_timeout = 1 } realm IPASS { format = prefix delimiter = "/" ignore_default = no ignore_null = no } realm suffix { format = suffix delimiter = "@" ignore_default = no ignore_null = no } realm realmpercent { format = suffix delimiter = "%" ignore_default = no ignore_null = no } realm ntdomain { format = prefix delimiter = "\\" ignore_default = no ignore_null = no } checkval { item-name = Calling-Station-Id check-name = Calling-Station-Id data-type = string } preprocess { huntgroups = ${confdir}/huntgroups hints = ${confdir}/hints with_ascend_hack = no ascend_channels_per_line = 23 with_ntdomain_hack = no with_specialix_jetstream_hack = no with_cisco_vsa_hack = no } files { usersfile = ${confdir}/users acctusersfile = ${confdir}/acct_users preproxy_usersfile = ${confdir}/preproxy_users compat = no } detail { detailfile = ${radacctdir}/%{Client-IP-Address}/detail-%Y%m%d detailperm = 0600 } acct_unique { key = "User-Name, Acct-Session-Id, NAS-IP-Address, Client-IP-Address, NAS-Port" } $INCLUDE ${confdir}/sql.conf radutmp { filename = ${logdir}/radutmp username = %{User-Name} case_sensitive = yes check_with_nas = yes perm = 0600 callerid = "yes" } radutmp sradutmp { filename = ${logdir}/sradutmp perm = 0644 callerid = "no" } attr_filter { attrsfile = ${confdir}/attrs } counter daily { filename = ${raddbdir}/db.daily key = User-Name count-attribute = Acct-Session-Time reset = daily counter-name = Daily-Session-Time check-name = Max-Daily-Session allowed-servicetype = Framed-User cache-size = 5000 } sqlcounter dailycounter { counter-name = Daily-Session-Time check-name = Max-Daily-Session reply-name = Session-Timeout sqlmod-inst = sql key = User-Name reset = daily query = "SELECT SUM(AcctSessionTime -
