Aside from our standard user pages, we also have "Person pages" where we put info about ourselves.
At my company (Cimpress/Vistaprint), we wrote a script to solve the problem of "Firstname Lastname" pages.
For each username, it looks up the person's real name in Active Directory (or LDAP, or whatever network credential system you use) and generates a redirect page for the person's full name. So it would look up Lwelsh, find the real name "Daren Welsh", and create an article [[Daren Welsh]] that contains "#REDIRECT [[User:Dwelsh]]". The script runs nightly to pick up any new employees.
If two people have the same full name, it generates a "Daren Welsh" disambiguation page that links to both people's user pages.
This has worked well for us for 3-4 years.
I strongly recommend this kind of solution instead of making "real name" pages that are different from the standard user pages. User pages are so integrated into the MediaWiki software, and it doesn't make sense to have two pages per person.
Hope this helps, DanB
