Accesing the Microsoft Exchange attributes with JNDI

Question

I have found that when you installl Microsoft Exchange 2003, it attaches some classes and attributes to the active directory default clases, in this page it is listed:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wss/wss/wss_ldf_AD_Schema_intro.asp
specifically im interested in the user class, it has an attribute called "auxiliaryClass" and in value it says "ms-Exch-Custom-Attributes Class" (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wss/wss/wss_ldf_classSchema_User.asp)
and finally in that clas i found the atributes that I need to access (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wss/wss/wss_ldf_classSchema_ms_Exch_Custom_Attributes.asp) but i dont know how to access asociated attribute-clases in active directory. I mean i can change the user description, because is a string, but when the value is other class?? how do i change it?
thx in advance (sorry for my english)

Answer 1

lol yes, i feel bad for asking that, i solved the problem 2 hours later...
but i dont understand how, the JNDI search inside the atributes and sub atributes for the class??? i know that really doesnt matther lol because it works and no more.
by the way i have other attribute, i can modify the email in the general tab in the user properties window in active directory, but i need to modify too the email in the "E-mail addresses" tab that appears when the user have a mailbox, especifically the SMTP type email, and dont know where is it, or by what name i can acces it
thx in advance :)
