Duo Proxy MFA Configuration with Leostream

Modified on Fri, 3 Mar, 2023 at 3:54 PM

The typical Duo Proxy RADIUS agent is setup to use "Active Directory/LDAP [ad_client]". This method would require Leostream to send the password along with the username + PIN (or PUSH). However, in our MFA RADIUS authentication workflow, the password is never provided. Because of this, we will need to leverage the [duo_only_client] method - below is an example of the configuration file:

;search_dn=


; SERVERS: Include one or more of the following configuration sections.
; To configure more than one server configuration of the same type, append a

skey=
skey
api_host=
