The following diagram shows the data flow that takes place during authentication.

Different types of authentication

DSS uses the following types of authentication.

●Windows

●LDAP

●Novell

Windows

Windows authentication uses Microsoft Active Directory, a database that contains information about objects, including users, that are contained within the domain. Active Directory provides an LDAP interface to the data in the directory database.

After a user provides valid credentials, the information is securely transmitted to the DSS server. DSS authenticates to the domain to validate the user credentials. If the user credentials are valid, DSS queries the LDAP directory for the authenticated user e-mail address. The LDAP directory supplies the e-mail address, and DSS inserts the address in the From field when the e-mail is sent.

LDAP

LDAP is a standard, directory-access, and message-oriented protocol. The client constructs a message that contains a request and sends it to the server. The server processes the request and sends the result back in a series of LDAP messages.
