Our zimbra implementation was fine, but today when users tried to login, they have a error. Looking in log I saw this error "user xxx (for example), account not found" . Users input only the username and password, now to login in fine, they have input username with domain and password. The version installed here is 6.03. How can I return to the first situation, users only input username and password to log in?

Example: Before - users input in webmail:
scardoso
*******

Now:
scardoso@codin.rj.gov.br
*******

Somebody could help me, please?
