Domain User Vs Authenticated User
To my understanding both are authenticated by the domain.
Domain user vs authenticated user. The everyone group includes all members of the authenticated users group as well as the built in guest account and several other built in security accounts like service local service network service and others. Any security principal from any trusted domain including guest accounts and does not include the anonymous logon system account. Authenticated users specifically does not contain the built in guest account but will contain other users created and added to domain guests. Authenticated users will contain all manually created user accounts in all trusted domains regardless of whether they are a member of the domain users group or not.
Authenticated users will contain all manually created user accounts in all trusted domains regardless of whether they are a member of the domain users group or not. This includes local user accounts as well as all domain user accounts from trusted domains. By default the authenticated users group is automatically added to the built in users group on all workstations when added to the domain. Authenticated users means exactly that any and all users which have authenticated to the system.
Everyone is any user account from the domain and any trusted domain including the guest iusr iwam accounts. Domain users a global group that by default includes all user accounts in a domain. Membership is controlled by the operating system. The authenticated users group contains users who have authenticated to the domain or a domain that is trusted by the computer domain.
Authenticated users includes any security principal from the local domain including guest accounts. Since mike is a member of users he is inherently an authenticated user. Any expert out there to clear up the confusion between domain and authenticated users. The authenticated users group can be used to grant permissions across a forest but domain users is a security group for users in a specific domain.
That would be any user that is a member of any group on your local system. Authenticated users a group that includes all users whose identities were authenticated when they logged on. This is because while the local user account includes the sid for the authenticated user group the local user must still authenticate to any remote computer prior to access being granted. In a domain environment this would be any user that is a member of any group on the domain.
