I also observe strange behavior on NIS and shared library.
A) 2.2-ALPHA
If I link the following program with libc.so.3.0, and run
% ./getpw username-in-NIS-map-and-not-in-local-passwd
then I get "sucess". But if link it with libc.so.2.2
(ln -s /usr/lib/libc.so.2.2 .; cc -o getpw getpw.c -L .)
then I get "fail". lib.c.2.0 gets "sucess".
I noticed this because old zsh and tcsh binaries don't work correctly
under 2.2 ALPHA.
The results of ktrace show it gets the right passwd field from yp
server but getpwnam returns NULL.
---
/* getpw.c */
#include <sys/types.h>
#include <pwd.h>
struct passwd *p;
main (int argc, char **argv) {
p = getpwnam(argv[1]);
printf("%s\n", p?"success":"fail");
}
--
B) originally 2.1.0, but kernel is current and some binaries are current.
The above program works fine for any shared library.
I cannot make out what is different between A and B.
