The Shadow package contains programs for handling passwords in a secure way.
Disable the installation of the groups program, as Coreutils provides a better version:
cp -v src/Makefile.in{,.orig}
sed -e 's/groups$(EXEEXT) //' src/Makefile.in.orig > src/Makefile.in
        Prepare Shadow for compilation:
./configure --prefix=/tools \
    --build=${CLFS_HOST} --host=${CLFS_TARGET} --sysconfdir=/etc
        The meaning of the configure options:
--sysconfdir=/etc
            
                Tells Shadow to install its configuration files into
                /etc, rather than /tools/etc.
              
Compile the package:
make
This package does not come with a test suite.
