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 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)
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.
