Hi, here is my problem: 0) Cisco APs - Radius - Ldap authentication via 802.1x - PEAP - MSCHAPv2 works. 1) I need to link the group of the user that try to authenticate with the SSID, so i can allow only a particular group of users to use a particular SSID/VLAN. 2) I have an OpenLDAP backend were all users and groups reside. users have, among others, objectClass posixAccount and sambaSamAccount. Groups have shadowAccount. 3) I DO NOT HAVE LDAPv3 SCHEMA FOR RADIUS ATTRIBUTES, so no objectClass radiusprofile for users. 4) A typical entry for user (relevant attributes): uid=username,ou=People,dc=mydomain,dc=it uid=<username> gidNumber=<gid> .. 5) A typical group entry (relevant attributes): cn=groupname, dc=mydomain,dc=it cn=<groupname> gidNumber=<gid> memberUid=<list of usernames> ... 6) I nave Cisco APs as NAS, with which i am able to send the SSID info, using vsa, to the radius server. From the request list I see: User-Name = "username" Framed-MTU = 1400 Called-Station-Id = "xxxx.xxxx.xxxx" Calling-Station-Id = "yyyy.yyyy.yyyy" Cisco-AVPair = "ssid=ZZZZ" Service-Type = Login-User Message-Authenticator = 0x8bded00fdb8decb62a26bc9c01f33938 EAP-Message = 0x02....... NAS-Port-Type = Wireless-802.11 Cisco-NAS-Port = "260" NAS-Port = 260 NAS-IP-Address = nnn.nnn.nnn.nnn NAS-Identifier = "apname" 7) I really connot figure out a correct configuration of: * ldap module in radius.conf * selection in users * mapping of group attribute in ldap.attrmap I try: (radius.conf, module ldap) filter = "(&(objectClass=posixAccount)(uid=%{Stripped-User-Name:-%{User-Name}}))" groupname_attribute=gidNumber groupmembership_filter = "(&(objectClass=posixGroup)(memberUid=%{Stripped-User-Name:-%{User-Name}))" groupmembership_attribute = gidNumber compare_check_items = yes (if i do not set this, all users with valid credentials can log in!)
