Custom Authentication Provider and User Details

[kmsheph]

I am unable to paste my code in so there may be some typos.
CustomProviderAuthentication

public class CustomAuthenticationProvider implements AuthenticationProvider {

@Resource DataSource dataSource;

public Authentication authenticate(Authentication authentication) throws AuthenticationException {
UsernamePasswordAuthenticationToken auth = (UsernamePasswordAuthenticationToken) authentication;
String username = String.valueOf(auth.getPrincipal());
String password = String.valueOf(auth.getCredentials());
Connection conn = null;
try{
   //In this call I use the username and password and pass them to my oracle proxy connection and then try to    connect to the database 
   conn = dataSourceAdapter.doGetConnection(username, password);
}
catch(SQLException sqle) {
 throw new BadCredentialsException(LoginException.handleLoginErrors(sqle));
}
//I use the same connection to get the granted authorities, user's role and user's id
return new UsernamePasswordAuthenticationToken(username, password,new GrantedAuthority[] {new GrantedAuthorityImpl(userRole)});
}

It works well for testing the database connection.

Is it possible to post your userDetailsService related java implementation classes, please?

Thanks.

[mdebac]

do you have implmentation for grants?

new GrantedAuthorityImpl(userRole)

Thanks.

Hi rhart,

as you mentioned in the code of class UserDetailsServiceImpl

public UserDetails loadUserByUsername(String username)
      throws UsernameNotFoundException, DataAccessException {
    try {
      User user = userApplicationService.findUserByUsername(username);
      return assembler.buildAuthenticatedUserDTOFromUser(user);
    } catch (NoResultException e) {
      throw new UsernameNotFoundException(e.getLocalizedMessage());
    }
  }

this method must return UserDetais object, I am not sure how can i do that....
Please help me as i am new to this.

Thanks in advance

Is what possible to modify the password before the authentication.

I've created a extended class of ´´DaoAuthenticationProvider´´ and initialized in security.xml:

<bean id="myAuthenticationProvider" class="es.gva.cit.terceros.security.provider.MyAut henticationProvider">
<security:custom-authentication-provider />
</bean>

But the definition of bean can't be accessible because of:

SAXParseException: cvc-elt.1: Cannot find the declaration of element 'beans'

What can I do to declare the bean element in the ´´security.xml´´ file?
Where I have to declare the new bean? And if i have to add this new bean to a ´´authenticationManager´´ bean and declare it too.
