[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:
$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.
