If you click on "Field" in the ADUC search dialog and in the pulldown menu on "user" (for example) you aren't able to get the fieldlist.
Created attachment 4192 [details] Update DisplaySpecifiers to provide the correct search fields and labels. The attached patch adds the correct labels to existing fields (such as "User", "Group" and "Contact") as well as adding new entries to support all the additional search fields within ADUC that were simply not present before.
Patch applied in commit d402866e31b9455f8d330c0f7e3ed52cbeebcb24. Note that there are still some issues regarding the ordering of the items in the fields lists. These are just sorting issues and are not related to the actual field list content. The sorting issues have been reported in bug #6393 and bug #6394. If there are still issues with the search field content, please reopen this bug.
