I have few questions Abt LDAP.


1) Can we access LDAP directory service directly through Java API's ?
if Yes - How ? if No - Why Not ?



2) LDAP protocol is NOT proprietory - True/False



3) LDAP servers Implement the protocol which makes it proprietory - True / False.



4) I have seen LDAP directory in weblogic 7.0 ,is it the actaul directory service ?

This directory was not there in earlier versions of bea then where exactly we had been storing the resources.



5)Which directory service websphere uses ?



6)is actual directory service comes with application servers



Your answers would be greatly appreciated.



thanks

I differ slightly with M. Bhiogade's responses. Here is my take:


  1. Although the Netscape LDAP is still in use, I would assert that it is deprecated by the JNDI APIs. The Sun com.jndi packages supply a generic JNDI & Directory Service API which I believe is more suited to Java than the Netscape API which is more driven by the original LDAP C API.
  2. LDAP is not proprietary. It is defined in part by RFC-2251 Lightweight Directory Access Protocol (v3). There are several supporting implementations, amongst them bwing Oracle, Sun and Microsoft.
  3. I am not sure what you mean by this, but of the three products mentioned above, all can be accessed by the standard JNDI implemntation of the LDAP protocol. This LDAP Browser uses the JNDI libraries to access LDAP servers and it seems to work across the board.
  4. I am not sure about this. I do not work with WebLogic.
  5. IBM WebSphere can plug into any fully compliant LDAP server, but I suppose the prefered one is IBM's own SecureWay LDAP.
  6. This depends on the application server. Every J2EE application server has a JNDI service, since it is required, but few actually ship with an actual directory service.
