I expect there are, at least, a lot of existing installations with "passwd: compat" in their nsswitch.conf, but probably most of them don't use NIS. I was under the impression that the only thing compat does is look for the +:::::: notation in /etc/passwd and forward to NIS. If so, or even if it's more complicated than that, maybe the Right Thing is to build a libnss_compat.so even when !BUILD_OBSOLETE_NSL, but have it error out on +:::::: rather than forwarding to NIS. The big problem I see with this idea is it might make it harder for TIRPC to drop in a replacement. Thoughts?
It is possible to redirect the lookup to something else besides NIS, using passwd_compat, group_compat, shadow_compat stanzas in /etc/nsswitch.conf.
Thanks, Florian
