Subject [Hadoop Wiki] Update of "IdeasOnLdapConfiguration" by SomeOtherAccount

Dear Wiki user,

The "IdeasOnLdapConfiguration" page has been changed by SomeOtherAccount.

--------------------------------------------------

  
  One key feature around LDAP is the ability to search objects using a simple, RPN-style system.
 Let's say we have an object class that has this definition:
  
+ { { {
  objectclass: node
  hostname: string
  domain: string
+ } } }
  
  and in our LDAP server, we have placed the following objects:
  
+ { { {
  hostname=myhost1
  objectclass=node
  domain=example.com
@@ -21, +24 @@

  hostname=myhost2
  objectclass=node
  domain=example.com
+ } } }
  
  We can now do an LDAP search with (&(objectclass=node)(hostname=myhost1)) to find the
'myhost1' object.  Similarly, we can (&(objectless)(domain=example.com)) to find both
myhost1 and myhost2 objects.
