My goal is to primary auth the user with LDAP then second auth with a duo push. Although the confusing part is there is RADIUS configuration required, even though I only want to use LDAP w/ Duo. Not sure I understand why but any configuration examples would be helpful!!
Here is mine today:
[ad_client]
host=1.2.3.4 (AD server IP)
service_account_username=ad-admin
service_account_password=ad-admin-password
search_dn=DC=domain,DC=com
security_group_dn="CN=Duo Checkpoint VPN,OU=Groups,DC=domain,DC=com"
[radius_server_auto]
ikey=ikey_from_duo_console
skey=skey_from_duo_console
api_host=api-123456789.duosecurity.com
radius_ip_1=checkpoint_gw1
radius_ip_2=checkpoint_gw2
radius_secret_1=secret1
radius_secret_2=secret2
client=ad_client
port=1812
failmode=secure
I am seeing the firewall logs that the radius server is not responding, but I am guess that just means it cannot properly authenticate my account. I know network-wise the gateways can reach the Duo proxy server.
