Dear All,

In the last few days i crate a single sign on thorugh windows live, and it's already worked like a charm. However, now i should to make sure that the system not supported multiple login in differnts place (for example one user login in two or more computers)

Any experience about this? what should i do ?

Hi Ridi,

I haven't tried it myself, but found a thread on the ASP.NET forum about disabling concurrent/simultaneous logins using membership providers:

http://forums.asp.net/p/1571186/3938613.aspx

There are loads of links and references on that thread... including:

... plus another ASP.NET forum thread on it here: http://forums.asp.net/p/1245799/2288756.aspx

Let us know how you get on!

Cheers, Lee.

Ridi,

I was just wondering if you were able to implement the single user with Umbraco. I am about to do the exact same thing for a subscription based site.

Thanks,

Justin

Hi Justin,

My solution is temporary, however here are the steps

Im creating a property in a member type, i called this as logged in flag with a datatype true/false

after that i create a login control that override onlogin event, by setting the property to true and create a Session for it

when they do a log off button you should override the also set the property to false and Sesions.abondon

furthermore you should aware the timeout of logged in, so you should take care of the Sessions timeout. Here are the two articles that good enough http://aspalliance.com/520_Detecting_ASPNET_Session_Timeouts and http://justgeeks.blogspot.com/2008/07/aspnet-session-timeouts.html
