Network Shell Script & Blade Logic & Network Security

I am going to take up a position in Data & Network Security.
I would need to write network shell scripts doing the following task:

Going to around 2000 servers and findout which groups has access to each servers and which ids are there in each group that has access.

I need to implement this automation using Blade Logic tool as well
I would appreciate if any one can provide some documentation and ideas how to achieve the above.

Your response is highly appreciated.

I'm unfamiliar with Blade Logic, but when it comes to network automation I go for Expect / TCL or Perl.
