  12           Build support for shadow password in /etc/shadow.  This file is only
  13           readable by root and thus the encrypted passwords are no longer

  21             If you leave this disabled, busybox will use the system's shadow
  22             password handling functions.  And if you are using the GNU C library
  23             (glibc), you will then need to install the /etc/nsswitch.conf
  24             configuration file and the required /lib/libnss_* libraries in
  25             order for the shadow password functions to work.  This generally
  26             makes your embedded system quite a bit larger.
  27
  28             Enabling this option will cause busybox to directly access the
  29             system's /etc/shadow file when handling shadow passwords.  This
  30             makes your system smaller and I will get fewer emails asking about
  31             how glibc NSS works).  When this option is enabled, you will not be
  32             able to use PAM to access shadow passwords from remote LDAP
  33             password servers and whatnot.

  39             If you leave this disabled, busybox will use the system's password
  40             and group functions.  And if you are using the GNU C library
  41             (glibc), you will then need to install the /etc/nsswitch.conf
  42             configuration file and the required /lib/libnss_* libraries in

  46             Enabling this option will cause busybox to directly access the
  47             system's /etc/password, /etc/group files (and your system will be
  48             smaller, and I will get fewer emails asking about how glibc NSS
  49             works).  When this option is enabled, you will not be able to use
  50             PAM to access remote LDAP password servers and whatnot.  And if you
  51             want hostname resolution to work with glibc, you still need the
  52             /lib/libnss_* libraries.
  53
  54             If you enable this option, it will add about 1.5k to busybox.
