Exchange 2013 with CU3 and silent redirection to different AD site

After updating Exchange 2013 CU2 to Exchange 2013 CU3, OWA silent site redirection feature become not available. The customer has two Exchange 2013 sites. Before we updated to CU3, user whose mailbox located on site A, could be automatically redirected to OWA on site A, after he logged on to OWA on site B. IE gives Error page and bring out link to the OWA page on site A. Here is screenshot about issue workaround.

Hopefully someone will help with some hint because it is quite anoying.

All other stuff works good, Outlook anywhere, autodiscover, only this remained.

Thanks in advance,
