Subject: LDAP question
Hello,

I am using Net::LDAP to connect my GroupWise Address Book and getting 
data from the Address Book.
This module is really good and help me a lot in getting user email ids.

I am small question:
I could figure it out what does cn and sn means and  search for first 
name and last name.

Is there a way to search for user defined fields in LDAP server? Like 
User Id, EmployeeID.

Could you please let me know any site where I can find description for 
Filter parameter.
for eg: sn means lastname, cn means name.

Thankyou in advance for your help.

Regards,

Ajay Lulia
