1.1 - Java and LDAP¶
Most developer will, at some point, face the tricky task to communicate with a LDAP server. LDAP seems to be a very simple technology, but when you get deep into it, you realize that many aspects are not well known, and not so easy to deal with.
Java is most certainly the number one language used in the enterprise, for around 10 years now. Some even call it the new Cobol !
Those two facts make it necessary to be able to communicate with a LDAP server in Java. This is ware a convenient API is useful, and this is why we decided to provide this API.
Of course, there are alternatives, like JNDI. We truly believe that those alternative aren't helping users to cope with the complexity of LDAP, at least they are not giving a hand to users. For instance, JNDI semantic are far awy from LDAP semantic. Let's see how different it is :
- Bind : used in LDAP to authenticate a user, and to create an entry in JNDI
- Unbind : close the LDAP session in LDAP, delete an entry in JNDI
- Compare : this LDAP operation is mapped to a Search in JNDI
- Various properties have to be set in JNDI in order to connect or tweak the Search operation, which is not convenient
- Attributes is case sensitive by default in JNDI, and they aren't schema aware
- Name in JNDI are not able to do a valid comparison in JNDI
- NamingEnumeration have to be explcitly closed in JNDI, as they aren't closed when you disconnect, leading to some resource leaks.
Some of those problems are also true for the existing LDAP API.
All in all, writing application including some LDAP operations in Java is just a painful task for most of the developers.
Our target is to provide a better API, that will help them getting efficient with their LDAP interaction.
