If the $PWDIR/security/passwd.adjunct file is present, C2 security is started automatically. ($PWDIR
is defined in /var/yp/Makefile.) The C2 security mode uses the passwd.adjunct
file to create the passwd.adjunct NIS map. In this implementation,
NIS allows you to use both the passwd.adjunct file and shadow file to manage security. The passwd.adjunct
file is processed only when you type the following.
# make passwd.adjunct
The make passwd command processes the passwd map only, not the passwd.adjunct map when you run make manually in the C2 security mode.
