Hello, i have got a realy annoing authentification problem and i would be glad if you could help me. I use a Cisco Aironet 1130ag Access Point, the radius-server is a Debian Squeeze (6.0.5) and i installed FreeRadius Version 2.1.10 from the packet sources. After i made some changes to the /etc/freeradius/modules/ldap to let my radius know where the LDAP is and some other things it looks like this: ----------> /etc/freeradius/modules/ldap ldap { server = 172.26.100.1 identity = "uid=binduser,cn=users,ou= Infrastruktur,dc=tarent,dc=de" password = xxxxxxxx basedn = "dc=tarent,dc=de" filter = "(uid=%{%{Stripped-User-Name}:-%{User-Name}})" base_filter = "(objectclass=posixAccount)" groupname_attribute = cn # groupmembership_filter = "(|(&(objectClass=GroupOfNames)(member=%{control:Ldap-UserDn}))(&(objectClass=GroupOfUniqueNames)(uniquemember=%{control:Ldap-UserDn})))" groupmembership_filter = "(&(objectClass=posixGroup)(memberUid=%{%{Stripped-User-Name}:-%{User-Name}}))" # groupmembership_attribute = radiusGroupName groupmembership_attribute = WLAN # compare_check_items = yes # do_xlat = yes # access_attr_used_for_allow = yes dictionary_mapping = /etc/freeradius/ldap.attrmap password_attribute = CleartextPassword set_auth_type = yes } when i start the freeradius with freeradius -X this is the output i get: FreeRADIUS Version 2.1.10, for host x86_64-pc-linux-gnu, built on Sep 11 2012 at 17:06:46 Copyright (C) 1999-2009 The FreeRADIUS server project and contributors.

Then i've read http://deployingradius.com/documents/configuration/eap.htmlbut i cant finde such a Validate Server Certificate option to uncheck. Now even if i am able to create a good certificate, i had to deploy it on about 500 Computers. Is it possible to use freeradius without such certificates? And if not, you might show me how to create a certificate and get this server running? Thank you in advance. With best regards, Florian
