Our RADIUS implementation is unable to send LDAP group information directly from an LDAP primary authentication source. You do have a few options here though:
1: ASA > [Duo RADIUS Proxy(Duo Authentication Proxy Reference | Duo Security) as primary] > NPS or other upstream RADIUS primary auth source that can send group info in a RADIUS attribute.
With this config you’d want to make sure to set the pass_through_all
option for both the RADIUS server and client configurations in the Duo proxy’s authproxy.cfg
file.
2: ASA > LDAP primary auth PLUS ASA > Duo RADIUS proxy only for secondary auth. The group info for assigning policies comes directly from your LDAP directory.
