Client name conversion in FTP user too restricted
I was attempting to move some test sites from our current manual solution to ISPConfig3. One client is "a-b", with a website "a-b.co.uk" and previously an FTP user called "a-b.co.uk".
I created an FTP user in ISPConfig3 for the client, entering .co.uk in the textbox. Yet the FTP username ended up as "a_b.co.uk". I tracked this down to convertClientName() in interface/web/sites/tools.inc.php: "only allow 'a'..'z', '_', '0'..'9'". Is there any chance to relax these requirements? Or will it cause problems elsewhere?
