Bug 35279 – preauth from admin console is broken after using Zmsetservername

I migrated from 4.5.10 to 5.0.13 using imapsync
for a while, new server name was newmail.domain.com
then I changed it to mail.domain.com via Zmsetservername
Also used zmprov mcf zimbraDefaultDomainName domain.com
Now when I try to check user's main via admin console, it uses preauth URL with domain.com , so I need to manually add "mail." to domain.com to be able to see user's mail.
