How to restrict 1 login per user at a time in windchill.
In other words I dont want same user to login from different machines or browser at the same time.
I don't think you can as there is no mechanism to do the checking built into the authentication process.
Are you using a SSO or Windchill DS?
Do you really want to do this? I use Windchill in a browser and inside Creo frequently. Restricting login to 1 per user id would require me to log out of one to access the other from my same desktop. Not productive at all!
Agree that you probably don't want to restrict. Very common to have a logged in session direct in a browser on one monitor and thru CAD in another browser.
