I am using Zimbra 5.0.10 on Ubuntu 8.04 on Xen 3.2. I have External LDAP Authentication setup against another server in my domain and that is all working fine.
However, I would like to create some mailboxes (support, info, etc) that are shared mailboxes between multiple users. As a result, I would like to avoid creating these mailboxes as "users" in my LDAP store. I believe, from various sources and specifically from the LDAP Auth wiki page (LDAP Authentication - Zimbra :: Wiki towards the bottom), that I should be able to create the account in Zimbra and *assign* a password (for normal users I do not assign a password so that they are forced to use the LDAP password) and avoid the user creation in LDAP.
Problem is, I get authentication errors when I try to log in as the user. Upon review of the LDAP logs, I can clearly see that Zimbra is attempting to look up the user in LDAP which is, obviously, failing. Is there a way to convince Zimbra that users auth'ing against just Zimbra are legit?
