Managing root user accounts
The directory server provides a default root user, cn=Directory
      Manager, that is stored in the server’s configuration file, such as under cn=Root DNs,cn=config.
About this task
The root user is the LDAP-equivalent of a UNIX superuser account and inherits its read-write privileges from the default root privilege set.
Steps
- 
To create or update root users, use the dscconfigtool.Example:bin/dsconfig create-root-dn-user --user-name "Joanne Smith" \ --set last-name:Smith \ --set first-name:Joanne \ --set user-id:jsmith \ --set 'email-address:jsmith@example.com' \ --set mobile-telephone-number:8889997777 \ --set home-telephone-number:5556667777 \ --set work-telephone-number:4445556666 Root user entries are stored in the server’s configuration. 
- 
To limit full access to all of the servers, create separate administrator accounts with limited privileges so that you can identify the administrator responsible for a particular change. Separate user accounts for each administrator make it possible to enable password policy functionality, such as password expiration, password history, and requiring secure authentication, for each administrator.
