Hi, For some aspects of fast-user-switching and face browsing it would be useful to be able to: 1. Query / store user photos (avatars) 2. Query user account status in an implementation/backend independent way (locked, expired etc) 3. Query the user's real world name etc (ie. not just gecos) 4. Receive user added / removed notifications 5. Receive user property changed notifications (picture / real name / etc changed) 6. etc As far as I can tell these things are either very difficult to do cleanly with traditional Posix APIs and in-band with NSS modules or not possible at all. Though I'd love to be proven wrong. I ran across something that looks somewhat interesting. http://developer.apple.com/documentation/Darwin/Reference/ManPages/man8/lookupd.8.html http://docs.info.apple.com/article.html?artnum=30770 http://aplawrence.com/MacOSX/macosxlookupd.html Darwin seems (at least from these docs) to use lookupd for some of this. Anyone have any experience with lookupd specifically? Or pointers to different solutions?
