I have noted that when I am importing requesters, the system is mistakenly importing users from an OU that I did not select.  As an example, I have a container called "IT", with a sub-container called "admin".  I selected IT, which automatically selects admin...I then unselected admin and performed an import.

 

The admin container is imported anyway, despite being explicitly unselected.  It seems that everything works fine if the root container is *not* selected, and sub-containers are.  When the root container *is* selected, the subcontainers are imported no matter what.

 

I am using version 7506 and IE7.
