How to change password using Spring LDAP and Spring security

问题

I'm using latest version of both Spring LDAP and Spring security. Also, I'm using annotation based configuration and I have no XML configuration files.

What I'm trying to achieve is really basic, I want to be able to allow users to change their password from my web application.

I've found that I could execute that request through DirContext.modifyAttributes. This method requires two attributes, the first one is the current userDn, which I'm not sure how to easily get through Spring. I'm pretty sure that there's a functionality to get it.

Then using a password Attribute as modification item for the second argument. Now, how can I know the password encoding that needs to be applied to the password provided by the user?

I've never used Spring LDAP / Security and a small, simple example would be awesome. Right now, I'm testing against in-memory ldap, but I'll have to switch to a real LDAP at the end of the week.

Thanks!

You need to use an instance of org.springframework.security.ldap.userdetails.LdapUserDetailsManager, it implements UserDetailsManager and has methods for changing user passwords. To instantiate it in your non-XML configuration, do something like this:

@Bean
public UserDetailsService getUserDetailsService() {
    return new LdapUserDetailsManager(); // TODO give it whatever constructor params it needs
}
