in my learning of AD DS Ecosystem I came across with this definition [link]:
By using the Windows Server® 2008 Active Directory® Lightweight Directory Services (AD LDS) role, formerly known as Active Directory Application Mode (ADAM), you can provide directory services for directory-enabled applications without incurring the overhead of domains and forests and the requirements of a single schema throughout a forest.
I don't quite understand what does it mean last sentence. The last month I started with AD DS for the very first time and now I'm securing a lot of meanings. I'm showing and summarizing you what I know and what I understand, so you can get an idea of my current knowledge:
- Directory: the structure.
- Directory Service: manager of a directory. Like a database manager but designed and enhanced for directories. X.500 is the most accepted and known standard set of protocols to define directory services.
- LDAP: most accepted and known protocol to define directory services that work over a TCP/IP network.
- AD
AD is a Microsoft database to store user logon and group information, and configuration information that drives group policy and other application software. (Active Directory explained)
AD DS:
Microsoft's Directory Server. (What is Active Directory Domain Services and how does it work?)
Set of services and applications provide for Microsoft to administrate resources, users, authentications, authorizations, etc. over a network.
- AD LDS: directory service belonging to AD DS.
- AD definitions I already know too: domain, domain controller, tree, forest and namespace.
- Schema: it defines object classes structures within a directory.
- Directory-enabled application:
A directory-enabled application is an application that uses a naming or directory service. (http://docs.oracle.com/javase/jndi/tutorial/getStarted/concepts/java.html)
Now, what does "you can provide directory services for directory-enabled applications without incurring the overhead of domains and forests and the requirements of a single schema throughout a forest." mean? What is a single-schema? Why is this an advantage?
Thanks in advance.
