manual.texi PASSWORD() issue clarified

The result is that the plaintext value @code{'biscuit'} is stored as the

password in the @code{user} table.  When the user @code{jeffrey} attempts to

connect to the server using this password, the @code{mysql} client encrypts

it with @code{PASSWORD()} and sends the result to the server.  The server

compares the value in the @code{user} table (the encrypted value of

@code{'biscuit'}) to the encrypted password (which is @emph{not}

@code{'biscuit'}).  The comparison fails and the server rejects the

it with @code{PASSWORD()}, generates an authentification vector

based on @strong{encrypted} password and a random number,

obtained from server, and sends the result to the server.

The server uses the @code{password} value in the @code{user} table

(that is @strong{not encrypted} value @code{'biscuit'})

to perform the same calculations, and compares results.

The comparison fails and the server rejects the

connection:
