My max user parm is set to 1050. I'm currently at 1038 this is causing major slow downs on the server. I looking for a way log off "idle" user logins with out having to do it individually. 
Why not set the TMOUT environment variable? Be sure to set the variable as read only so that individual users cannot override it. If users time out, the get booted.
I have done a few test runs and this seems to work for me. Will it also work for people already logged in?
How could it? It's an environment variable for the current shell. You need to set set this in a common profile.

I justed wanted to be certain. Is there a way to limit the number of concurrent sessions for a user?
If you can, force your users to log out. Make the change, then allow them back in.
