It looks like a new feature in version 6 is "View Accounts" which will show you all objects (accounts, aliases and distribution lists) for a particular domain. If a domain has enough objects to fill more than one page, the first page will display the domain objects, but as soon as you click Next, it will show all objects for all domains.
It seems that a suitable workaround is to simply perform a basic search for all object types for that particular domain. I just want to know if this could be related to installation/configuration issue or if it is a bug.
This was tested on the following version: Release 6.0.2_GA_1912.RHEL5_64_20091020145322 RHEL5_64 NETWORK edition
