Two people, one username, at the same time

[Marcio Ferreira]

Hi,

today my JahiaSite allow my users login using the same username at the same time.
I want to deny this possibility.
I want to do something like that:
1) I login with user XPTO
2) Another person try login using XPTO
3) My session is blocked.

Or:
1) I login with user XPTO
2) Another person try login with XPTO
3) The second person is blocked.

There is an away to configure any of this possibilities on Jahia?

Thanks,
