ISPconfig 3.1.6: shell user can not be the same for other servers
short description
I should be able to create a shell user with a name already in use on an other server.
In earlier version this issue was the also for web sites and databases, but fixed in the meantime.
When trying to create a shell user with a name already used on a other server I get
"The username must be unique."
correct behaviour
It should be allowed
environment
Server OS: centos Server OS version: centos6 ISPConfig version: 3.1.6
