Huh? I really didn't expect this question. Of course the in-process caching is still present. Read the new chapter called "Caching" in the document I attached to my OP. Or, even better, I just quote it here, for your convenience: ======= Caching ======= The information fetched from file or the Windows account database is cached by the process. The cached information is inherited by child processes. While usually working fine, this has some drawbacks. Consider a shell calling `id'. `id' fetches all group information from the current token and caches them. Unfortunately `id' doesn't start any child processes, so the information is lost as soon as `id' exits. But there's another caching mechanism available. If cygserver is running it will provide passwd and group entry caching for all processes in a Cygwin process tree, which first process has been started after cygserver. So, if you start a Cygwin Terminal and cygserver is running at the time, mintty, the shell, and all child processes will use cygserver caching. If you start a Cygwin Terminal and cygserver is not running a the time, none of the processes started inside this terminal window will use cygserver caching. The advantage of cygserver caching is that it's system-wide and, as long as cygserver is running, unforgetful. Every Cygwin process on the system will have the cygserver cache at its service. Additionally, all information requested from cygserver once, will be cached inside the process itself and, again, propagated to child processes. > > * db_separator in /etc/nsswitch.conf > > I can't see a pressing need for configurable separators here.

Eric's mail on this is pretty enlightening. Corinna -- Corinna Vinschen Please, send mails regarding Cygwin to Cygwin Maintainer cygwin AT cygwin DOT com Red Hat
