That won’t work; subscribers can’t upload. And if the same user is logged in from a different machine with a higher level account type that does allow editing, editing will be disabled.
You’re asking for huge amounts of WordPress trouble, along with security implications for the site and all users. Just assign all users their own account.
Thank you SongDog
Correct, I should have said I am using a role editor to create multiple subscriber groups, and a subscriber group that can only upload specific file types.
The rub is that the client insists that “other WP websites let multiple users login using the same login credentials”, and I need a concise, non-tech response either confirming this or explaining why it is ill advised.
If all the subscribers are doing is reading or downloading a file, NO EDITING, does it matter how many of them are logged in at the same time using the same login?
And, if all the students in the class (say 25) are logged in simultaneously using the same user credentials, and they are all uploading a file simultaneously, can WP handle it?
It’s bad security and they’re asking for trouble. If they don’t understand security, too bad.
Try the same login with multiple browsers (needed because of login cookies) and confirm if it works. If 25 students are using the site at the same time, be sure you’ve got the hardware to support that. WordPress itself is not an issue; it can scale, given the hardware (like anything). I.e., a free webosting account will be slow; a server on a LAN at the school should be OK.
