[Note: I'm new to using Macs, with a previous history of being a Windows Power User. I use Mac OS X v10.4 - Tiger] During the first time boot of the Mac, I setup a single user account (which by default is the administrator). Now I decided to add some user accounts and did that in 'Apple->System Preferences->Accounts'. I also disabled auto-login for the default user. The 'Other accounts' option in this preference dialog is still disabled. Initially I thought I probably did something wrong, but when I tried to create the same account again, it said that the account already exists. I've also tried logging out of my default (administrator) account. It does not show the other users in the login dialog - it shows only the administrator account! As a last ditch effort I also restarted the Mac - it still shows only the administrator account in the login dialog! Why wouldn't it show me the accounts I've created? Now I can't login as any other user! The home directories for the new users are seen under /Users/. Neither the included help documentation nor the Apple support site have any information about this. Any help would be appreciated!
