CR3 is released. You should try that instead. http://www-933.ibm.com/support/fixcentral/swg/doSelectFixes?options.selectedFixes=4.0.0.0-IC-Multi-TDISOL-CR3-LO73535&continue=1
TDISOL is just the method to load the users/sync users.
Note, I had issues with CR2, and used CR1 as a fix. CR3 is an option that should work in your case.
