Method Detail

hasPassword

public boolean hasPassword(String user)

Description copied from interface: PasswordProvider

Returns true if this provider considers itself responsible for the given user name. In general, if this method returns false, then checkPassword will return null or false for all possible passwords. However, some providers (like the LDAP provider) may create a user to synchronize with some backend during a call to PasswordProvider.checkPassword(String, String, boolean). PasswordProvider.hasPassword(String) will not do this. This is typically only of importance during PasswordProvider.changePassword(String, String) since a provider which is not responsible for a password should not attempt to change it, and before a provider has not created a user, it is also not responsible.

checkPassword

public Boolean checkPassword(String user,
                             String password,
                             boolean readOnly)

Description copied from interface: PasswordProvider

Authenticates the give user given the password token. May return a null Boolean in order to signal that this provider is not responsible for the given user and can make no decision. Concrete implementations may decide to return false for all unknown users. If readOnly is false, then some implementations may choose to create new users.
