Case Sensitive ldap.jar Java application

We has Java/J2EE application, when user login with the given ldap.jar validating the password with bind

ldapCon.bind(ldapVersion, dn, pword.getBytes("UTF8"));

But it is not taking password case sensitive, it is allowing me to login with both Rama1234 and rama1234

When i googled come across the below content

**********************************
In eDirectory 8.7.1 and 8.7.3, when you enabled Universal Password, the password was case-sensitive only when you logged in through Novell Client32. The password was not case-sensitive when you logged in through other clients (for example, eDirectory SDK or iManager).

Appreciate your thoughts ....
