The "IdeasOnLdapConfiguration" page has been changed by SomeOtherAccount. http://wiki.apache.org/hadoop/IdeasOnLdapConfiguration?action=3Ddiff&rev1= =3D1&rev2=3D2 -------------------------------------------------- = One key feature around LDAP is the ability to search objects using a simp= le, RPN-style system. Let's say we have an object class that has this defi= nition: = + { { { objectclass: node hostname: string domain: string + } } } = and in our LDAP server, we have placed the following objects: = + { { { hostname=3Dmyhost1 objectclass=3Dnode domain=3Dexample.com @@ -21, +24 @@ hostname=3Dmyhost2 objectclass=3Dnode domain=3Dexample.com + } } } = We can now do an LDAP search with (&(objectclass=3Dnode)(hostname=3Dmyhos= t1)) to find the 'myhost1' object. Similarly, we can (&(objectless)(domain= =3Dexample.com)) to find both myhost1 and myhost2 objects. =20
