Yeh. Though users are readonly they are still users in the site. In Alternatively you can use EnsureUser method by parsing userlogin

Do you get users from groups also? or just users added individually to site?

@Anonimous,
This is getting all the users in the site including user in groups but if you have LoginName it is better to use EnsureUser("domain\Loginname")

Is there a way to get the current logged in user's username? I have a 3rd party web app that's running in a SharePoint environment and needs to log in automatically using the SharePoint username when the site is accessed.
