Allow hideUserNotFoundExceptions property to be set in AuthenticationManagerBuilder

Summary

I'm using the LdapAuthenticationProviderConfigurer for my spring security LDAP configuration.

Actual Behavior

Actually, i don't find a way to set the hideUserNotFoundExceptions property in the built LdapAuthenticationProvider (by LdapAuthenticationProviderConfigurer)

Expected Behavior

Allow hideUserNotFoundExceptions property to be set in auth .ldapAuthentication() without redefining a complet LdapAuthentificationProvider

@Autowired
	public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
		auth
			.ldapAuthentication()
}

Configuration

@Autowired
	public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
		auth
			.ldapAuthentication()

			.userDnPatterns(securityProperties.getLdap().getUserDn())
			.groupSearchFilter("(uniqueMember={0})")
			.groupSearchBase(securityProperties.getLdap().getGroupDn())
			.userDetailsContextMapper((customUserDetailsContextMapper())

			.contextSource(contextSource())
			.rolePrefix(ROLE_PREFIX)
			.passwordCompare()
			.passwordAttribute("userPassword");


	}

Version

1.5.1.RELEASE

Sample

Start with AuthenticationManagerBuilder.ldapAuthentication(), then follow LdapAuthenticationProviderConfigurer to the LdapAuthenticationProvider it builds and inspect how provider properties are exposed. Done means the LDAP configuration can set hideUserNotFoundExceptions without redefining the provider.
