where is zimbraAuthMech attribute in domain configuration, where I can define how users will be authenticated -- internal Zimbra LDAP, external AD or LDAP, etc.
At previous (6.x) version this attribute was possible define as Both -- in this case Zimbra first try to auth via external AD, if not -- via internal LDAP.
After upgrade to 7.1 zimbraAuthMech cann't be defined as "Both". Only zimbra, ad, ldap, kerberos5 or custom
How I can setup in 7.1 mixed authentication scheme, like it was at 6.x?
