• The utilities will work properly whether shadowing is enabled or not.

• The utilities have been slightly modiﬁed to support Red Hat’s user private group scheme. For a

description of the modiﬁcations, see the useradd man page. For more information on user private

groups, turn to Section 5.4.

• The adduser script has been replaced with a symbolic link to /usr/sbin/useradd.

• The tools in the shadow-utils package are not Kerberos, NIS, hesiod, or LDAP enabled. New

users will be local only. For more information on Kerberos and LDAP, see Chapter 10 and Chapter

18.
