I have taken over a site developed by someone else.
It uses a Dynamic User Directory (4.0.10) which shows a custom search when logged in (works OK) but when no user is logged in displays a A - Z links to filter by first letter.
For the life of me I cannot figure out where the A-Z filter is configured.
The problem is that it seems to be filtering on the user contact name.
I need it to filter on Display Name
