Cisco ISE authentication Using LDAP + OTP ( external server that sends SMS To the User )

Drthrax — Fri, 13 Mar 2020 14:43:02 GMT

Hi ,

I am deploying ISE to Posture VPN users ( ASA is the NAD ).
I want the users to be authenticated using LDAP ( which is already configured in ISE ) in addition I want the User to receive an OTP via SMS using an external server . Can this be done and if yes kindly state the document or procedure

thank you !

ISE : 2.6

Hi , Thank you for the reply ,
Actually I want to do authentication on both ISE ( LDAP )and the external Source that will send an OTP via SMS .
Do you think this is feasible ?
The links u sent are using are mainly using ASA to do 2FA , and the second is for complete authentication with external server .

Let me look what i have posted is correct or not.

your requirement is VPN authenticated with Radius (here is ISE+LDAP) MFA you want to be SMS is this correct.

The URL has information for Multifact authentication, you can use Duo for the same.
