ssh base Two factor authentication

Hi, 

we are using ssh base two factor authentication by adding the patch openssh-two-factor-auth.patch on 

Centos 5.6 Linux server.

One factor is username/password and second factor is  passphrase/ssh key.

I used the below guidline for this.

We want to replace this machine with Solaris 10.I tried to compile openssh on solaris with openssh-two-factor-  auth.patch but unable to complete in success.

Is there any way on solaris ssh to force the ssh that it should validate both factor (username/password and passphrase on key) before log in.
