Our company use F5 BIG-IP APM (Access Policy Manager) VPN Gateway to authenticate remote access user. It is now an requirement to implement OTP (One Time Password) as an authentication method for the VPN client. We already have an Microsoft Active Directory in place and also installed the Safenet Authentication Manager Service to use OTP Hardware token.   According to the F5 BIG-IP VPN Technical document, it can use OTP authentication by pointing to a RADIUS Server instead of to the MS Active Directory.

My question shall we install the Network Policy Service (provided by Microsoft) as a RADIUS service or use the Safenet OTP Plug-in ?

Also, what is the high level step-by-step procedure for setting up such implementation ?

Appreciate you kind advice in advance.

Maybe you can check out Safenet integration with F5 (guide - "Using SAS as an IDP of F5 BIG-IP APM Integration Guide"), it has the step through screenshot to configure APM. F5 APM must support Challenge/Response mode for Radius authentication.  Ensure that the RADIUS server is configured to recognize the APM as a client. Use the same shared secret in both the RADIUS server configuration and in the Access Policy Manager configuration.

the APM should be having the flow of
client (browser) >APM logon page(using otp as password) > Safenet Radius auth  >APM Resource assignment (based on Safenet auth check resp)

(PDF file name - 007-012607-001_SAM_IntegrationGuide_F5-BIG-IP-APM_RADIUS_RevA.pdf)

Specifically for the OTP, catch the "Configuring the SAM Connector for OTP Authentication"
- inside the Safenet AAA server, in the "Token Policy Object Editor",  Connector for OTP Authentication should be enabled
- also under the "Connector for OTP Authentication", set the parameters (e.g. Authentication Code, etc) for the OTP Authentication connector.
