>Description:
If you're using NIS, and there is a `+'-line in /etc/passwd after a
`+@'-line, getpwent doesn't enumerate all entries, i.e. it stops after
processing the `+@'-line. This is a problem with samba-2.1.0-prealpha
that tries to build a hash-table of all users using getpwent.
>How-To-Repeat:
Add a `+@<netgroup>' and a `+' line to the /etc/passwd file. You can then
use a simple program, for example:
#include <sys/types.h>
#include <pwd.h>
struct passwd *p;
int main() {
setpwent();
while (p = getpwent()) {
printf("name: %s\n", p->pw_name);
};
}
(Another weird thing: some entries are listed twice when I try this on
my machine).
>Fix:
Except for creating a huge netgroup with all users, no solution known.
