dynamic VLAN assignment w/ mschapv2 against AD and LDAP

[schilling]

Hi All,

The group helped me configure the freeradius server to do mschapv2
against ldap w/ ntPassword if user sign on with username at foo.edu, and
to do mschapv2 against AD w/ ntlm if user just sign on with username.
Now I want to go one more step further - passing on some attributes
back to NAS. Basically, I want to achieve
If (ldap authorization) {
    if (ldap.employeeStatus = facstaff) {
        REPLY{'Service-Type'}            = "Framed-User";
        REPLY{'Tunnel-Type'}             = "VLAN";
        REPLY{'Tunnel-Medium-Type'}      = "IEEE-802";
        REPLY{'Tunnel-Private-Group-Id'} = "facstaff";
    } else { # no ldap.employeeStatus attribute or ldap.employeeStatus
!= facstaff
        REPLY{'Service-Type'}            = "Framed-User";
        REPLY{'Tunnel-Type'}             = "VLAN";
        REPLY{'Tunnel-Medium-Type'}      = "IEEE-802";
        REPLY{'Tunnel-Private-Group-Id'} = "student";
    }
}else { # ntlm authentication
    REPLY{'Service-Type'}            = "Framed-User";
    REPLY{'Tunnel-Type'}             = "VLAN";
    REPLY{'Tunnel-Medium-Type'}      = "IEEE-802";
    REPLY{'Tunnel-Private-Group-Id'} = "facstaff";
}

What's the easiest way to accomplish this? unlang? perl module? Where to start?

Thanks,

Schilling

the other one against ldap ntpasswd hash possible?

Got the whole setup working. So basically if users sign on with
username at foo.edu with eap, they will be sent to ldap w/ ntpassword
authorization. If users sign on with username only with eap, they will
be sent to active directory w/ ntlm authentication.
configuration changes are the following:
etc/raddb/proxy.conf add
   realm foo.edu {
   }
   realm NULL {
   }
/etc/raddb/site-enabled/inner-tunnel at the ldap line in authorize section add
   switch "%{Realm}" {
       case foo.edu {
           ldap
           #see /etc/raddb/module/mschap if ntpassword available,
then do not use
           #NTLM_auth
           update control {
               MS-CHAP-Use-NTLM-Auth := NO
           }
       case NULL {
           mschap
       }
   }

etc/raddb/module/mschap, etc/raddb/module/ntlm are all from integrate
with Active Directory howto.
