Customizing the Name in the Welcome Message in the Portal 
Use
When a user logs on to the Enterprise Portal, his or her 'friendly name' is displayed in the welcome message in the portal header. This friendly name, for example, John Parker is constructed from the user's first and last name in the corporate LDAP directory. If you wish, you can change which attribute from the corporate LDAP directory is used for the welcome message.

Procedure
Result
When a user logs on to the portal, the name in the welcome message will be drawn from the attribute in the corporate LDAP directory that you specified.
