Hello,
I am having some trouble getting Busybox to authenticate against LDAP. I do not
see Busybox calling glibc's getpwnam() when I do an ltrace, and consequently I
don't see /etc/nsswitch.conf being opened. I only see an open and read of
/etc/passwd.
This is Busybox 1.4.0 with glibc 2.5, the relevant config options are:
CONFIG_FEATURE_SHADOWPASSWDS=y
# CONFIG_USE_BB_SHADOW is not set
# CONFIG_USE_BB_PWD_GRP is not set
I passed the LDFLAG of -lnsl to Busybox, don't know if that is required but I
have confirmed that the binary is linked to libnsl. Here is an strace of a
login attempt.
read(0, "testuser\n", 4096) = 9
open("/etc/passwd", O_RDONLY) = 4
fstat64(4, {st_mode=S_IFREG|0644, st_size=221, ...}) = 0
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =
0xb7dae000
read(4, "root:x:0:0:root:/root:/bin/sh\nss"..., 1024) = 221
read(4, "", 1024) = 0
close(4) = 0
munmap(0xb7dae000, 4096) = 0
time(NULL) = 1179339627
rt_sigprocmask(SIG_BLOCK, [CHLD], [], 8) = 0
rt_sigaction(SIGCHLD, NULL, {SIG_DFL}, 8) = 0
rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
nanosleep({3, 0}, {3, 0}) = 0
time(NULL) = 1179339630
write(1, "Login incorrect\n", 16) = 16
How can I make Busybox use nsswitch.conf and look up entries in ldap? I have
openssh compiled and working with it so I do not believe this is a
configuration issue with the system.
Thanks!
Jari
