Sophos UTM: Two-factor authentication with Duo Security

Hello,

I'm having a hard time to configure the two-factor authentication with Duo Security.

Following this KB : https://community.sophos.com/kb/en-us/127334

-> Here's the configuration of the proxy file :
[ad_client]

;IP DC

host=192.168.10.2

service_account_username=administrator

service_account_password=password

search_dn=DC=labo,DC=lan

security_group_dn=CN=techgrp,OU=Technique,DC=labo,DC=lan

 

[radius_server_auto]

ikey=ikeyDuoxxx

skey=skeyDuoxxx

api_host=api-duoxxx

;IP utm sophos :

radius_ip_1=192.168.10.100

radius_secret_1=password

failmode=safe

client=ad_client

port=1812

 

Sophos UTM : 

 
 
 
2017:09:08-16:21:57 utm1 aua[23485]: id="3006" severity="info" sys="System" sub="auth" name="Spawned child for authentication test"
2017:09:08-16:21:57 utm1 aua[23485]: id="3006" severity="info" sys="System" sub="auth" name="Bind test request: radius"
2017:09:08-16:22:02 utm1 aua[23485]: id="3006" severity="info" sys="System" sub="auth" name="Bind test failed. Method: radius, error: DENIED
2017:09:08-16:22:02 utm1 aua[23485]: timed out waiting for packet"
 
Can anyone help me or share a working configuration ?

  • I have duo security successfully working, but your going to be limited in what you can do with it.

     

    We can only get it to work with push notification and nothing else (using windows 10 standard vpn) as well there is only like a 10 second time period before windows closes the connection request. We say to our staff they need to have the application open, so they can accept the request within the 10 seconds.

     

    We have a windows radius server installed on our domain controller, which the DUO proxy authenticates incoming connections against.

     

    UTM > Duo Proxy > Radius > Active Directory

     

    What you should first do is have the radius server setup and working with the Sophos first, when you get that working, then look at adding the duo proxy.

     

    I need to document our setup, so I will do a guide in the next few days. Let me know if you have any questions in the mean time.
