Question

I am currently using asp.net membership database on multiple apps. I am not looking for single sign on function. My desire is to be able to logged in at the same time on multiple apps.

But currently, when I log into one app, the other one is logged out instantly. I think the apps issues some kind of Token inside the database so when I log into one app, the other one logs out.

How can I get around this thing?

Answer 1

• Do your applications share a
  machineKey?
• Do they all target the same membership database?
• Do they share one cookie domain?

Here’s part of how I implement it

<httpCookies domain=".domain.com.ar"/>

<authentication mode="Forms">
  <forms defaultUrl="~/" loginUrl="~/login" timeout="43200" protection="All" domain=".domain.com.ar" cookieless="UseCookies" />
</authentication>

And my membership, roleManager, and profile providers all target the same databases.
Do this in every application, of course.

Note: I know, I know. The machineKey article is deprecated, but it still has a very valid C# example of how you should generate your machineKey.

They should be formatted like so:

<machineKey validationKey="128 hexadecimal characters" validation="SHA1"
            decryptionKey="64  hexadecimal characters" decryption="AES" />
