[Samba] Samba crashes on password change from Windows 2000 clients

[Markie]

Hi, i'm not subscribed to the list so could you please Cc back to me :)

Just discovered this problem today when my brother tried to change his
password. Windows sat there and eventually said that my domain couldn't be
found or something, this seemed very odd so I had a look in the logs and got
this show up...

For a few times whilst windows was sitting there. I've had a look in
util_sec.c and it appears to be happening somewhere around here, no?

static void assert_gid(gid_t rgid, gid_t egid)
{
        if ((egid != (gid_t)-1 && getegid() != egid) ||
            (rgid != (gid_t)-1 && getgid() != rgid)) {
                if (!non_root_mode()) {
                        DEBUG(0,("Failed to set gid privileges to (%d,%d)

                                 (int)rgid, (int)egid,
                                 (int)getgid(), (int)getegid(),
                                 (int)getuid(), (int)geteuid()));
                        smb_panic("failed to set gid\n");
                        exit(1);
                }
        }
}

Can anyone suggest what's going on here? I've got a group 0, wheel, and
Samba is running as root.
