If you want to create a new administration user with the same rights as cn=admin,cn=Administrators,cn=config, create the new user in the group cn=Administrators,cn=config. All users in this group are subject to a global ACI that allows the same access as the Directory Manager.
You cannot use DSCC to perform this task. Use the command line, as described in this procedure.
Create a new administration user.
For example, to create a new user cn=Admin24,cn=Administrators,cn=config, type:
$ ldapmodify -h host1 -p 1389 -D cn=admin,cn=Administrators,cn=config -w - dn: cn=admin24,cn=Administrators,cn=config changetype: add objectclass: top objectclass: person userPassword: password description: Administration user with the same access rights as Directory Manager.
The -D and -w options give the bind DN and password, respectively, of a user with permissions to create this entry.
