Couple months ago I start using Zimbra (upgrade from 8.0.7 Network Edition to Open Source 8.5.1_GA_3056.FOSS few days ago) until now I have only one domain (domain1.com) and it's works great. Now I decided to add another domain (domain2.com), but problem occurs. Domain is working, users can receive and sent messages, but user can't log in zimbra webmail. I continuously receive the error " The username or password is incorrect. Verify that CAPS LOCK is not on, and then retype the current username and password".
What should I do?
