In Windows Server 2003 Active Directory there was no UI to access the FullName field - see this blog post for a discussion of this, and how Display Name is not the same as Full Name.
In Windows Server 2008 Active Directory, the Full Name field can be seen on the General Properties section of the User windows in ADUC.
The Full Name field is used in the Global Address List. I have found that in some cases the Full Name field has been populated with the username, rather than the full name, meaning that users can't find these colleagues in the GAL as they are out of order.
I want to extract the username and FullName fields from AD so that I can find all the accounts where the two fields are the same (I'm not trying to do this comparison with an LDAP query - I can do it in Excel once I extracted all the values).
However, I can't find anywhere how I would actually refer to the field labelled "Full Name". Does anyone know?
