There are "u" user accounts on the ldap server
We have a number of "s" services that use LDAP to manage user account.
Each service has particular attributes
Each service must be able to access only it's information
Basic services use only the information contained in the standard LDAP
useraccount
Advanced services have dedicated OUs with special attributes
It is important that each service can accees in RO (no modification) to
only it's information.
That's why we made our LDAP as it is in the attached picture.
