Hi,

I have requirement where if two users logged in with same userid and password from two different machines at the same time then it should not allow second user to get into the system. It means only one user can login at one time from one machine.

Thanks in advance.

Seems obvious, just a part of authentication, with one more result. What's the problem? What did you try? Do you have any authentication at all? If so, what you need is nearly that same, isn't it?

You can do this may managing a table for Loggedin Users....with a column called loggedInStatus(1/0)
.. at the time of login check if loggedInStatus is true then..do not logged in user..

However you could also use the System.Web.Caching.Cache object to track a users current session as well. If finding the info in the cache object fails fall back to reading it from the DB then place that info in the cache for the benefit of subsequent requests.

Solution 2

Save the current user in session or in the memory,when any user login,check the state of the user.
