Hi all
I have found one big problem with Let'sEncrypt plugin with mpm-itk module.
Plugin create shared folder under /var/www with rights www-data:www-data. Main problem is that this folder unreadable from client domains cause mpm-itk prevent reading any files that not complain client user id and group id. Any web cal just get 403 Forbidden and in this case certs issuing does not work completely.
Possible solution is create .well-known/acme-challenge dirs under each client home folder and direct all domains and subdomains registered at this client account to this folder. I do not now is it possible but sounds like a solution.
P.S. Sorry for miss of thread category. I think this thread should be under plugins Support
