Ok, I posted this problem already on this list, but now I tried to do
some other things...
My setup is: I have one computer running Linux, which is connected to
Internet and receives mail for my domain sjc.dhis.org. There is
another computer (also Linux) which is connected to the first with a
network.
Now all the users of my school do have an entry in the /etc/passwd
file on the second computer. This file is shared over NIS (Network
Information System) to the first computer.
NIS is configured on the first PC, and the users can log in
succesfully. I made the following programm to asure that NIS
functioned with /etc/passwd:
=====
#include <stdio.h>
#include <pwd.h>
#include <sys/types.h>
int main (int argc, char *argv[])
{
struct passwd *pw;
if(argc != 2)
{
fprintf(stderr, "Usage: getpwnam username\n");
exit(1);
}
pw = getpwnam(argv[1]);
if (pw != NULL)
{
printf("username:\t%s\n",pw->pw_name);
printf("password:\t%s\n",pw->pw_passwd);
printf("uid:\t%d\n",pw->pw_uid);
printf("gid:\t%d\n",pw->pw_gid);
printf("gecos field:\t%s\n",pw->pw_gecos);
printf("homedir:\t%s\n",pw->pw_dir);
printf("shell:\t%s\n",pw->pw_shell);
} else
fprintf(stderr, "User \"%s\" not found!\n", argv[1]);
exit(0);
}
=====
Ok, when I run this,
first on a normal user (which got a 'real' line in /etc/passwd)
=====
kvack:~# ./getpwnam kbr
username: kbr
password: x
uid: 1000
gid: 1000
gecos field: koen breugelmans,,,
homedir: /home/kbr
shell: /bin/bash
kvack:~#
=====
and then on a user which exists only on the second computer, and is
known on the first one using NIS:
=====
kvack:~# ./getpwnam test
username: test
password: x
uid: 1002
gid: 100
gecos field: testgebruiker,,,
homedir: /home/users/test
shell: /bin/nologin
=====
Ok, it seems to me that this is working like it should.
Now, the exim part...
For local delivery, exim looks up the user using the getpwnam()
function (at least this is what I read in the documentation). The
programm I used to show wheter NIS works, also uses getpwnam().
So I assume there is no difference...
But when I try to send mail to for example 'test' (the NIS user), I
get the following:
=====

=====
Ok, the localuser director failed...
and this is what I don't understand... it uses getpwnam(), which works
like it should, and still localuser don't works. (PS it does works for
users listed in /etc/passwd on the system itself, like 'kbr' in the
first example...).
Finally, the lines in my /etc/exim.conf for localuser and
local_delivery:
=====
local_delivery:
driver = appendfile
group = mail
mode = 0660
mode_fail_narrower = false
envelope_to_add = true
file = /var/spool/mail/${local_part}
...
localuser:
driver = localuser
transport = local_delivery
=====
If somebody can help me , I would like to hear about it...
Thank you very much...
