    you are correct:

    "SERVER_ENCRYPT

    Authentication takes place on the server.
    Passwords are encrypted at the client machine
    before being sent to the server."

    Hi Rahul,

    Answer D is correct becouse if "SERVER_ENCRIPT" then user name and password both are sent via network to server in incripted formate.

    "If you want to protect the user ID and password from eavesdropping, use
    authentication type SERVER_ENCRYPT so that both user ID and password are
    encrypted."

    from v8 info center : http://publib.boulder.ibm.com/infoce...79%70%74%22%20

    If authentication is SERVER, the *user ID and password* are sent from the client to the server so that authentication can take place on the server. The value SERVER_ENCRYPT provides the *same behavior* as SERVER, except that any *passwords* sent over the network are encrypted.
