[pmwiki-users] Prefix session files with the id:

[kirpi at kirpi.it]

We have a small wiki locked with AuthUser.
Sessions are stored in a /work.d/ directory with names starting with "sess_"
Would it be possible to prefix those files with the id: instead (or in
addition) so that one can know who is logged in just at a glance?
Otherwise, one have to manually open all the files...
Or, is there a better way to show logged-in users?

Thank you
Luigi
