What specifically would you like to know? Essentially local authentication means that you are bypassing Active Directory in favor of creating your own users and creating your own permissions. It can be especially cumbersome for very large organizations that typically rely on Active Directory.

Maybe the following article will help you: http://onlinehelp.tableau.com/current/server/en-us/help.htm#security_net.htm
Specifically, "Passwords are communicated from browsers and tabcmd to Tableau Server using 512-bit public/private key encryption. Tableau Server sends a public key to the browser, which uses the key to encrypt the password for transmission. Each encrypted transmission uses a key one time before it is discarded. This means that passwords are always secured regardless of the use of SSL. If SSL is enabled, SSL encryption is used in addition to the 512-bit public key encryption of passwords."
It's exactly which i wanted to know. thanks a lot!
