Hi, I followed the installation of this tutorial: "Installing A Web, Email & MySQL Database Cluster On Debian 6.0 With ISPConfig 3", however, installed NGINX web server instead of Apache web server, and it worked ... however, in part described as: "5 Configure Replication In ISPConfig" in step "Then open System > Server Config and enable the checkbox "Connect Linux userid to webid" on the "Web" tab:" this option is not listed in the panel ISPConfig3 ... This option is only for the Apache web server? Thanks to all!
