Check Text ( C-39530r1_chk )
Verify the root user is configured as a role, rather than a normal user. # egrep '^root:' /etc/user_attr If the returned line does not include "type=role", this is a finding. Verify at least one local user has been assigned the root role. # egrep '[:;]roles=[^;]*,?root([,;]|$)' /etc/user_attr If no lines are returned, no users are permitted to assume the root role, this is a finding.

Fix Text (F-34021r1_fix)
Convert the root user into a role. # usermod -K type=role root Add the root role to authorized users' logins. # usermod -R root
