The PAM module is using a NSS module directly which isn't allowed.  The
NSS modules don't provide a user ABI, only the nSS routines in libc are
allowed to use them.

Just to show that it is possible, this is the same module on my RH
system:

$ ldd /lib/security/pam_unix.so 
	libnsl.so.1 => /lib/libnsl.so.1 (0x4002d000)
	libcrypt.so.1 => /lib/libcrypt.so.1 (0x40043000)
	libc.so.6 => /lib/i686/libc.so.6 (0x40070000)
	/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)
