Bind DN/Username: Username used to connect to the LDAP service on the specified LDAP Server. If of the form accountname@domain. com, the username is transformed into a proper LDAP bind DN like CN=accountname, CN=users, DC=domain, DC=com when accessing the LDAP server. Sometimes the default transformation does not generate a proper bind DN. In such cases, a fully formed and valid bind DN must be entered. Password: Password used to connect to the LDAP service on the specified LDAP Server. Base DN: The starting search point in the LDAP tree. The default value will look up the 'defaultNamingContext' top-level attribute and use it as the search base. Authentication Filter: Filter used to look up an email address and determine if it is valid for this domain. The filter consists of a series of attributes that might contain the email address. If the email address is found in any of those attributes, then the account is valid and is allowed into the Barracuda Email Security Service. Mail Attributes: Enter the LDAP attributes you want to use (ex: mail, proxyAddress, etc. ).

Use LDAP for Authentication: Enable or disable authentication of email recipients using your existing LDAP server. Once you have entered information about your LDAP server, click the Test Settings button to ensure that the Barracuda Email Security Service can communicate with the server.
