I built our first Zimbra installation using a secondary domain we own so that we could test before cutting over completely. We also configured LDAP external authentication. Everything worked beautifully so we decided to migrate.
In that process I added our "real" domain and then changed all accounts to use that domain vs. our test domain. All authentication appeared to fail at this point.
The workaround is to log in with our domain appended to the account on the login page. In other words, I used to log in as "troy" but now I have to log in as "firstname.lastname@example.org". Even the admin account requires this because I changed the domain there as well.
What can I do to have it work without providing the domain?
By the way, I maintained the other domain but as aliases...
