Active Directory Users

[Mohammad Abohelal]

Hi all

 

I need help with simple configuration to authenticate windows active directory users via free radius. 

 

I have a domain controller, Cisco vpdn router , and free radius  UNIX environment  ( FreeBSD ) 

 

Active directory group: VPDN, user name's have allow dialin on user option 

 

Radiusd.conf ldap configuration: 

 

      ldap {

 

            server = "ad.xxx.yyy"

            identity = "CN=radiusd,OU=External_Object,DC=xxxl,DC=yyy"

            password = radiusd111

            basedn = "OU=VPDN_USERS,OU=External_Object,DC=xxx,DC=yyy"

            filter = "(uid=%{Stripped-User-Name:-%{User-Name}})"

            base_filter = "(objectclass=radiusprofile)" 

 

      

When I try to connect via l2tp dialer I get error:  (auth: Failed to validate the user  ( 

 

 

modcall: leaving group authorize (returns ok) for request 0

  rad_check_password:  Found Auth-Type LDAP
