Today I've created a new client together with a new site. Everything seemed to word right. When I was using "chown" to change change a file for the new created user I reconised, that the group was changed but the new ownername was different to that I was given to it. Than I had a look in passwd and there I could find that the given name was taken from a user which was created before and this user had the same UID as my new user. So o found that one UID was given to two differend users. At least I found three UIDs which were used by six users. Every UID started over 10.000. It seem to me, that ISPConfig does'nt check realy if a UID is allready given or not. That sounds like a security risk. How ISPC ist giving new UIDs and how could this story happen?
