Record Management and National Archives compliance?

Summary

How do you deal with removed/denied users after the 5-year NARA requirement?

Content

As a Federal Government agency, our Privacy & Records Management group in the General Counsel has taken issue with LearnCenter keeping users past the 5-year training data requirement for users who have been removed or denied.  They want us to determine if there is some way to delete these users from the system completely, but I don't know of any Learning Management System that will allow this.  Does anyone know if this can be done in Learn?  Or, if you are another Fed, how are you addressing this issue with your records management group?
