Indeed. The other thing I was thinking about would be something like
struct switchuid { uid_t uid; uid_t uid_range; gid_t gid; gid_t gid_range; };
int setswitchuids(size_t size, struct userids list[]); int getswitchuids(size_t size, struct userids list[]); int switchuid(struct userids *);
However, this is very non-standard and the cances of this getting implemented are very low, I guess. The reason I am asking this is that I am considering hacking Apache and the kernel for UID swtching - wondering if it should be a quick&dirty local hack, or something reasonably clean so I can try to get it integrated into Linux and Apache.

Aha, that would be SCM_SETCREDENTIALS ? I'm curious about this. It seems to be the easiest (and most probable) solution for now.
