First: congratulations about Zimbra!
Second: I tried to search in Wiki, Forums, documentation and Google .. but i donīt found a solution!
Third: I have the following environment: Zimbra 4.5 running on CentOS authenticating users in MS AD.
Now, my problem...
The problem is that the "SamAccountName" in AD differs that "Account Name" in Zimbra, and then users cannot authenticate.
My MS AD account is: firstname.lastname@example.org (a registration code)
My zimbra account is: email@example.com with an alias called firstname.lastname@example.org
So, if atuthentication configured in Zimbra is "Internal", the users can authenticate with alias, but if is "External Active Directory" this not works!
My questions: The alias can be used for authentication in MS AD??
How can i configure Zimbra to use the alias to authenticate users in MS AD??
If i invert the alias with the account name, the authentication is successfull, but the address that is sent in messages is not the valid one (the alias is sent in from field).
