[SOLVED] disable user edit

Hello,
for a simple site, our customer wants to have one user account for all users. The want to distribute some kind of member cards, all with identical user credentials, that give their customers access to some benefits. They don't want to use a .htaccess because this can't be styled and in Joomla itself there seems to be no way to prevent users from changing their passwords or their email address. I'm thinking about something like a demo site setup, that has one user account for all users which they can't edit.
Is this possible with community builder?

So you want to have a single generic account with no profile edit? That should be doable using CB Auto Actions and just redirecting away from profile edit. The below should work.

Global
Triggers: onBeforeUserProfileEditDisplay
Type: Redirect
User: Automatic
Access: Non-Moderators
Action
URL: index.php?option=com_comprofiler
Message:
There isn't really an official means of flat out turning off profile edit, but this should prevent them from reaching profile edit at least.

Thank you very much, this should do the trick. I did the same for onBeforeNewPassword and onLostPassForm to prevent users from resetting the password of the account too.
Have a great day
Markus
