IBM Exam S1000-007 Topic 9 Question 58 Discussion

The 'chadmin' command can be used to modify the attributes of a user account, including the groups that the user belongs to. The syntax for limiting root user access to members of the group called 'system' would be:

sql

chadmin group=system root

This command will add the root user to the 'system' group and remove it from any other groups. Members of the 'system' group will be the only ones able to access the root account.
