User synchronization between CWIS and a Drupal 7 instance requires
both this CWIS plugin and a companion plugin on the Drupal 7 site.
Currently the cwis_user Drupal plugin only supports Drupal 7.x and
will not with with any other Drupal versions.

Copy the contents of cwis_user in this folder into a folder called
'cwis_user' under 'sites/all/modules' in your Drupal installation.
Copy objects/RestAPIHelper.php file from your CWIS directory into that
folder.

Configure both the CWIS DrupalSync plugin and the Drupal cwis_user
plugin, giving them the same syncronization password and filling in
the URLs of the remote sites.

User synchronization is now enabled.  Newly created users on either
site will be mirrored into the other site.  Logging in to one site
will mirror the login on the other site so that it's not necessary to
log in twice.
