I notice that for normal login, users do not have to enter full email address as long as their url match their email address domain. This is made possible by setting up the virtual host in Admin Console.
However, this virtual host function seems unable to work when I check [Must change password]. User logging to Zimbra will get prompt to enter a new password twice. However, Zimbra will keep prompting that the username or password is incorrect despite entering every field correctly. Unless of course, user enter their full email address!
Can someone verify if this is also the case for their zimbra setup?
