Managing Accounts and Domains 79

SMTP over TLS/SSL settings If SMTP over TLS/SSL is enabled then passwords will not be sent in

clear text if both sending and receiving systems support TLS/SSL. If

one system does not support TLS/SSL, then traffic between the

systems will not be secured/encrypted.

If you enable this option and an LDAP connection cannot be made or

the StartTLS LDAP command is not supported or disallowed, then the

LDAP connection fails.

LDAP Port The LDAP port used to communicate with the Exchange server. By

default, this port is 389.

LDAP / Exchange Username The username for the LDAP/Exchange server.

To determine the fully-qualified username, open Active Directory, go

into Active Directory Users and Computers and double-click on the

user account in question. Under the Account tab, use the User Login

Name plus the @xxx.xxx that follows as the LDAP username.

LDAP / Exchange Password The password for the LDAP/Exchange server.

LDAP Filter The custom LDAP filter to apply to this domain (optional).

LDAP Search Base The starting search point in the LDAP tree. The default value looks up

the 'defaultNamingContext' top-level attribute and uses it as the

search base.

If you have two domains under one forest, and you want to

authenticate both domains using the same LDAP server, use an

LDAP search base of DC=com and LDAP port of 3268. This allows

for a complete search under the .com domain and a Global Catalog

default connection.

LDAP UID

This specifies an attribute of the LDAP container found using the

LDAP filter and which provides the Barracuda a unique identifier

to associate with user accounts on the Barracuda. This is

primarily used for Alias Unification and Single-signon. Typically

this is uid, or on more recent Active Directory schemas

sAMAccountName.

LDAP Primary Email Alias

When Unify Email Aliases is enabled this LDAP container

attribute provides the account name under which quarantined

messages are stored and for which the actual recipient address is

an alias of. For Single-Signon using LDAP (and when Unify

Email Aliases is enabled), this is the account that users will be

directed to when logging in with any of their aliases. This

attribute is almost always mail, and should be a fully qualified

address with a local part, an "@" sign, and a domain component

which is configured on the Barracuda as a valid domain.

Canary Email

This email address is used to determine if LDAP lookups are

properly locating valid and invalid email addresses for this

domain during the normal operation of the Barracuda. If at

anytime the provided canary address is not found in the LDAP

directory then LDAP recipient verification (Exchange

Accelerator) and Unify Email Aliases will be disabled for the

duration of the failure.
