In my LDAP Client program sometimes I have to include the DN value within the search filter. But this DN is changing frequently and every I have to change this filter in my code.

When I googled it for that I got something like this

Suppose you want to pull all users of ObjectType = Person from the R&D and HR ous, but not any users from Marketing and PM. The filter would be:

(&(objectClass=person)(|(ou:dn:=ResearchAndDevelopment)(ou:dn:=HumanResources)))

Can anybody explain this more in detail?
