I can't easily answer "why does SAS need this?". I don't know SAS well
and it is a huge octopus of dozens of modules with all sorts of
features. The lack of it doesn't prevent SAS from launching, and it
can't be something major or we would have heard complaints by now. 
The best I could get out of their tech support is a link to a support
article: http://support.sas.com/learn/le/notes/15/231.html. Reading it
doesn't clarify the issue for me at all. I have no idea if the
referenced functionality is relevant to MIT users.

Before we deploy yet another change to cluster, can we test what doesn't work?  Or is it that the application truly doesn't launch at all?  (If so, I'm curious what happened for the last 2 years).
