    8 config FEATURE_SHADOWPASSWDS
    9 bool "Support for shadow passwords"
    10 default n
    11 help
    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
    14 publicly readable.

    16 config USE_BB_SHADOW
    17 bool " Use busybox shadow password functions"
    18 default y
    19 depends on USE_BB_PWD_GRP && FEATURE_SHADOWPASSWDS
    20 help
    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.
    34
    35 config USE_BB_PWD_GRP
    36 bool "Use internal password and group functions rather than system functions"
    37 default n
    38 help
    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
    43 order for the password and group functions to work. This generally
    44 makes your embedded system quite a bit larger.
    45
    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.
