I've done some basic testing of this on Oracle on a fresh install.
The UI looks great!
I've committed a small change to merge.tcl, which was erroring out of the users created content in the system.
The biggest issue I ran into so far is, I noticed that the object reassignments are handled in /packages/acs-authentication/tcl/local-procs.tcl. That doesn't seem right. The object reassignments must be handled regardless of what authentication is being used. I think this code should be moved, either directly into /packages/acs-admin/www/users/merge-final.* or to a library in /packages/acs-admin/tcl/.
