User synchronization between CWIS and a Drupal instance requires both
this CWIS plugin and a companion plugin on the Drupal side. The CWIS
plugin needs to be enabled first, so that it can create DB tables that
both plugins use.  Once enabled, the CWIS plugin needs no additional
configuration. 

To install the drupal plugin, copy the 'cwis_user' folder into the
'modules' folder of your drupal instance.  You'll also need to copy
'sync_common.php' into the 'cwis_user' folder.

After that, the Drupal plugin needs to be enabled.  Log in to your
drupal site as an administrator. From the main menu (along the left
side of the page in the default Drupal theme), you will need to select
Administer / Site building / Modules.  Then, tick the box next to the
CWIS_User module description and hit 'Save configuration' at the
bottom of the page.

Next, the Drupal plugin needs to be configured.  From the main menu,
select Administer / Site configuration / CWIS User.  You'll then need
to enter the CWIS database information.

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.
