public class PasswordAuthentication extends Object implements AuthenticationMethod
AuthenticationMethod interface for more details.
The username is the E-Person's email address,
and and the password (given to the authenticate()
method) must match the EPerson password.
This is the default method for a new DSpace configuration. If you are implementing a new "explicit" authentication method, use this class as a model.
You can use this (or another explicit) method in the stack to
implement HTTP Basic Authentication for servlets, by passing the
Basic Auth username and password to the AuthenticationManager.

public boolean canSelfRegister(Context context, javax.servlet.http.HttpServletRequest request, String email) throws SQLException
The configuration key domain.valid is examined in authentication-password.cfg to see what domains are valid.
Example - aber.ac.uk domain : @aber.ac.uk Example - MIT domain and all .ac.uk domains: @mit.edu, .ac.uk
