userPassword Problem
hi all,
I have used LD AP Browser/Editor for creating userPassword attribute.
But i have a problem here while reading this attribute. When i read this
attribute with the openldap ldapsearch utility it works fine. But when i
try and read this userPassword attribute with JNDI it gives me some
garbage characters and then these characters change everytime i run the
program. All the other attributes are being read properly through JNDI.
Can anybody guess what the problem is ?? Can anybody using JNDI for
reading userPassword attribute help me out by sending the code for
doing the same. My code is attached .
Thanks in advance
