One user, two email domains, one AD authentication domain
We are running one ZCS 7.1 OSS server for two different company domains. All of our email authentication passes thru an Active Directory server where each user is a member of each domain.
My problem is, I have 5 users with email address for both company1 and comapny2. Let say email@example.com and firstname.lastname@example.org. Is it possible for email@example.com to authenticate with AD of firstname.lastname@example.org.
In general, can I have two different email accounts authenticating with the same LDAP or AD server that has a different domain name?
