[development] user_save() trying to create a duplicate user

Here's an example from my CAS module.

         // Become user 1 to be able to save profile information
          $admin = array('uid'=> 1);
          $user = user_load($admin);

If you're operating as a normal user you'll want to save away the  
value of the current user, become admin , do your save stuff, then  
become the normal user again. Something like:

    global $user;
    $temp_user = $user;
    $admin= array('uid' => 1);
    $user = user_load($admin);

    ... do some save stuff

    $user = user_load($temp_user);

This of course should only be used when you're trying to circumvent  
permissions checked by user_save() (do you have permissions to modify  
user roles for example).

I thought there used to be code in cron.php to do this, but I think I  
may just be remembering wrong. Perhaps someone else on the dev list  
could answer the question of who the cron user executes as.

As I said, not 100% sure this is your problem, but I do know you'll  
have problems having generic users sync up their roles unless you do  
this permissions escalation.
