How to costumize the MastHead with different attributes from LDAP?

Hello,

I am using NW 04.

My Portal is connected to an LDAP, which it takes the users from there. When a user logges-in the Masthead says: "Hello <first_name> <last_name>".

The <first_name> & <last_name> parameters are taken from the LDAP Server.

Now, I would like to take a different attributes for <first_name> & <last_name> which exsists at Active Directory to display at the portal.

I have downloaded the current MastHeah iView from:

System Administration -> Support -> Support Desk -> Portal Runtime -> Browse deployment

And imported it into the NWDS.

I am stuck at this point, since I can't find how this iView takes the <first_name> & <last_name> parameters and how I can change it to take different ones.
