NB 8.1.2 Automate client installs

We automate the installation of new clients for both Windows and Unix from build servers in their associated environments but now with the new security features in NetBackup 8.1.2 a token is required during the installation process. Is there an existing process that can be used to obtain the needed token?

There has to be companies with large deployment environments which have the same needs. I can't see them doing this one server at a time. I know that I can generate a token that is good for an extended period of time and uses but what happens when either one of them expire, can the token be regenerated? If there has to be an easier way than to create a new one and update the build scripts to use the new token.

In case it matters my master is running NBU 8.1.2 on Solaris 11. 

Thank you.
