Here is the list Supported Authentication Schemes Combinations:

2. GuiDBedit Tool 

It will be used to configure Multiple Authentication Schemes to allow the administrator to request multiple proofs of user's identity. In our case, for example, request the user to install his certificate and enter his AD password for authenticating.

GuiDBedit Tool will be found at C:\Program Files (x86)\CheckPoint\SmartConsole\RXX\PROGRAM\GuiDBedit.exe

3. Verify the first factor authentication is Certificates.

It will be found at Tables -> Network Objects ->network_objects.
Found the Gateway / Cluster object, in this case , for example, it is R77.
From lower pane, check the value of realms_for blades-> ssl_vpn ->authentication-> auth_schemes->Element Index 0 -> auth_scheme.
It is certificate which is configured before thorough Smart Dashboard.

4. right click on 'auth_schemes' ,-> 'Add...'

5. Enter a value for Index:  

1 for the second authentication scheme. 0 is already there for 1st factor, which is 'Element Index 0'

6. Go to 'Element Index 1', right click on 'auth_scheme' -> 'Edit...'. Choose 'user_pass' for AD username and password as 2nd factor.

7. Save the changes ('File' menu - 'Save All').
