Person Document question

I am not a Domino Administrator and have a quick question.  I am looking at the person document under the basics tab and see the username renhan\PeaceHealth on the first line and, Renee Hansen on the second line.  The shortname is renhan. This is a web application. We want the user to log into this application using renhan because this alias is used for her NT account and users are use to this format.  When I use the following code  in a computed field,  @Name([CN];@UserName) it shows renhan but I want this to show Renee Hansen.  How can I pull the second line in the username field under the basics tab.  Thanks in advance for your help.

I’m afraid that the “real” user name (@UserName) is the one you certified: CN=renhan/O=PeaceHealth. All of the rest are just aliases. You’ll need to perform a lookup in order to get Renee’s “human” name (FullName[2]).
