More than one UserDetailsService registered. Please use a specific Id reference in <remember-me/> <openid-login/> or <x509 /> elements

Question

I am attempting to enable remember me functionality using spring security

<bean id="userService" class="mypath.service.UserDetailsServiceImpl" />

<security:http auto-config='true'>
  <security:intercept-url pattern="/Login" filters="none" />
  <security:form-login login-page='/Login' authentication-failure-url="/Login?login_error=1"/>
  <security:remember-me data-source-ref="dataSource" />
</security:http>

However, I seem to have specify the userService somewhere in the remember-me element ? How do I do this.

The error I am getting on starting tomcat is

More than one UserDetailsService registered. 
Please use a specific Id reference in <remember-me/> <openid-login/> or <x509 /> elements.

Answer 1

Ok it wasn't that hard, just in case anyway else finds the spring documentation rather challenging to navigate:

<security:remember-me data-source-ref="dataSource" user-service-ref="myUserService"/>
