collision between shell/ftp accounts and client accounts named webXX is not checked
Naming scheme collisions in ispconfig backend
Consider having created a client named web10. The standard naming scheme for ftp users is [CLIENTNAME] As soon as you have reached 9 websites - which generate users named web1 web2 and so on, An add of a ftp/ssh account collides with the default naming of website users.
The result is rather drastic: As soon as the cron tries to add the shell user web10 e.g. - the website-user web10 gets removed and no new user is added ispconfig.log just states useradd: Benutzer »web10« existiert bereits
Apache wont restart due to suexec/suphp entries apache2: bad user name web10 New changes are not accepted afterwards also.
