Ldap bind mechanism in java

Question

Hello all,
Im facing find solution for ldap bind similar to [ldap_bind|http://php.net/manual/en/function.ldap-bind.php] function in php.
it seems easy and nice.
I had look around the web and some forums and got direction to use this
But this is not similar solution as in php.
ldap_bind use only conection, userName and password dont know nothing about password hash method and will verify credentials as valid or invalid.
Anyone have informaiton or ideas how to do it in java?

Answer 1

You don't need to know the LDAP hash at all to do a bind and user password check. That's against security - why would a administrator let anyone know what hashing he uses - thats letting an important piece of your security out (even though thesemodern hashes are pretty much ir-reversible)
All you need is use Sun JNDI code to do a bind , use authentication method Simple and then gives user's id and password in clear-text. Directory server will itself take care of converting clear text password passed by you and comparing it with hashed user password in LDAP.
From your code perspective if you get a DirContext back - your bind was successful otherwise you will get a NamingEnumeration exception.
try reading through DirContext InitialDirContext ... just do a random search and you should get numerous helper code over internet.
