Method Detail

authenticate

public boolean authenticate(User user,
                            java.lang.String password)
                     throws javax.naming.NamingException

Throws:

javax.naming.NamingException

isRepeatedLoginAttempt

public boolean isRepeatedLoginAttempt(java.lang.String normalizedUsername)

Returns true if there were already 3 login attempts within the last minute with this username

getLoggedInUserBySessionCookie

public User getLoggedInUserBySessionCookie(play.mvc.Http.Session session)

Retrieves the logged-in user from Play's session. If a user is logged-in their username is stored in Play's session cookie. With the username a user can be retrieved from the database. Returns null if the session doesn't contain a username or if the user doesn't exist in the database.

In most cases getLoggedInUser() is faster since it doesn't have to query the database.

getLoggedInUser

public User getLoggedInUser()

Gets the logged-in user from the RequestScope. It was put into the RequestScope by the AuthenticationAction. Therefore, this method works only if you use the @Authenticated annotation at your action.

writeSessionCookie

public void writeSessionCookie(play.mvc.Http.Session session,
                               java.lang.String normalizedUsername)

Prepares Play's session cookie for the user with the given username to be logged-in. Does not authenticate the user (use authenticate() for this).

isSessionTimeout

public boolean isSessionTimeout(play.mvc.Http.Session session)

Returns true if the session login time as saved in Play's session cookie is older than allowed.

isInactivityTimeout

public boolean isInactivityTimeout(play.mvc.Http.Session session)

Returns true if the session inactivity time as saved in Play's session cookie is older than allowed.
