WebApp Sec: Ber encoding for ldap response control.

[Babu Kopparam <babukopparam () gmail com>]

Hi!

I am using JNDI for LDAP Binding (passing userid and password while creating initialcontext) for authentication purpose.

In case, the user's password is expirying in x days, i am getting a response control from the context object where the 
control has the value which is BER Encoded.

Can some one tell if there is any freeware / opersource project which gives me the BER Decoder.
OR if this is very simple program, can you share the same with me ?

Thanks in advance,
-Babu.
