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

/lib/libnss_* libraries.
