It depends on what you are doing. It's a fairly quick and easy way to separate users on (eg) web hosting - by having Apache execute each site as a specific user. Yes I'm sure there are better and more secure ways of doing it, but when you inherit a setup where you have to trust each customer not to take a peek around other customer's sites (and grab their DB access credentials from the Wordpress config file) then it's a big step forwards ! And regardless of how you separate users, having an exploitable privilege escalation flaw means that someone compromising one of your customer's sites is then able to escalate their privileges to do more damage than they could from an unprivileged account. _______________________________________________ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
