title: Spring LDAP, check the membership of user in specified group
body: <p><br /> I'm creating an app with a special privileges for a user which is in specified group in LDAP, I'm logging in using spring security, but I have no idea how to check the group of the user.<br /><br /> The goal is to show all of the ldap users table with data, and if someone belongs to a group in ldap it shows also buttons to change that data.
  <br /><br />
  So how to check belonging to group of an LDAP user?</p>
