IDT 4.1 AD authentication to multiple CMS servers

Hello All, Quick question on IDT, We have Windows AD/SSO setup to BOBJ systems.

From client tools (IDT and Rich client) we can log on to Development system using Windows AD after we generate Keytab file and place it in client machine along with Krb5 and bscLogin.conf files..

Now if we want to logon to Sandbox and QA BOBJ system using Windows AD then what is the best option ? I tried combining the files with dev sandbox and QA information but that did not help so thought of opening a discussion here..

Thanks

Raj.
