Centera 4.3 question

I try out to find out the following:

1. Is there anyway we can set the idle timeout value for centera viewer to 15 min?

2. What is the SSH version used by Centera 4.3?

3. Can we set password policy for the local account?   If it cannot be done can we setup AD and use AD server to enforce the password policy?

4. Can I set ssh session timeout value?
