I'd like to know if you need a license file for running CA Directory
12.0 SP18 CR6 with CA Single Sign-On ?
You don't need any License file as it has its 
"license bits of code removed a while back." 

CA Directory/SiteMinder License Validation 

So said, as long as you've got your legal contract enforced for it,
you can run it.
