Readers fields, don’t ya just love ’em. They are great when they work properly and if you stick to a few simple rules they normally work with no problems.
1. Never use common names in a readers field.
2. Never mix Users / Groups or Roles in a single readers field.
3. Remember that the server must have the OU/O structure as the user.
Why do I currently hate readers fields? Well try getting them to work in an R5 environment that has a hierarchial server structure and flat user structure. Two of the rules are broken immediatly so you explain to the customer that it’s not a supported environment. Then they point you to a second database where they work fine. I can’t find out why . . .
