You can use the LDAP auth module and in the Admin console set the configuration to use external LDAP.(Also you can use LDAP referrals)

When authenticating to an external ldap server, make sure to check the dynamic user profile creation property if the user profile does not exist and also make sure to set the appropriate search attribute in the administrator service(User Search Key and User Search Return Attribute), the default is cn. If the default is left on all the user profiles would be created with the profile name default.
