Get error after changing user id in passwd.

I recently changed some user id's in passwd to match some backed up files I had and now when an account is suspended I get the following message when trying to view their site.

Could not determine user from environment

Anyone seen this, and does CPanel store user id's in some file?

Thanks;

 

Never mind. After about 10 minutes, the message went away and the normal suspended page appeared. Strange.

Peace;
