Restricting user accounts - temporarily

[Sulphy]

Hey guys,

So i have an odd question. This is to affect thousands of accounts, so it should be easy to unpick. 

 

In a nutshell, I need to come up with a viable solution to lock down user accounts to only a couple of dedicated systems and web sites. ie email etc.

The users come in over VPN, and usually have loads of memberships in AD. I assume, that the user policies apply after the VPN has authenticated the user - am getting verification on that piece.

 

My thinking, was to inject an attribute to the AD accounts affected, and using MIM, find that attribute, and move the user to a new OU, that has disabled inheritance, with a unique policy applied that locks down certain apps from running, only allow a subset or URL's they can run, disable all network shares access etc.

 

Do you think this would work? 

 

OR

 

Does anyone maybe have a simpler process i can look into. Again, this is temporary, and need to be able to undo it easily.... we are talking around 22,000 accounts.

 

Appreciate any thoughts / ideas.
