bookmark ssh in ssl vpn portal

Hello all,

our costumer use ssl vpn web portal with bookmark widget on fortigate 100d 5.2.

He want to connect via ssh to a linux server where he put these commands to have two-factor authentication:

GssapiAuthentication

ChallengeResponseAuthentication

Now he wants to create a ssh bookmark pointing to this server, but the 2-factor authentication doesn’t work(the connection ask only for user and pass).

I think the only way that it could work is to use port redirect bookmark, there are any other way to make it work?
