Ldap help please

Please see the picture below, You can see my domain tree and what i have entered, i dont understand what im doing wrong.

I have also tried these settings =


This will get me logged in, it will also map my users that I want it to, but on the group mapping I get the error stating



Test: Group Mapping

A small list of groups is selected for you to review. When you are finished close this window.

Status: Error

No groups were found using the specified configuration. Try changing the base DN,group filter or member field.


I dont get what this means? any help please?

if i try to put just my base of my domain dc=piper;dc=com for the “base DN” it will get a error finding users… im so close to getting this and its driving me nuts.
