Prevent login of same user from different machines

[hbarca]

Hello,

I would like to prevent the same user to log in in the portal from different machines, either by doing a forced logout on the first machine or by not permitting a second login on other machine. Is there a simple configuration setting to achieve that using the standard IdentityLoginModule? Or do I need to overwrite the IdentityLoginModule?

Thank you for any advice.
Horia.

Does anyone have an idea how to do this?
I still did not find anything on this issue.

Thank you for any idea.
