Everyone knows that SID, he is a laugh riot - Sorting it all Out - Site Home

Here is thst big list of well-known SIDs, the bulk of which are localizable and a significant number of which are localized.

Note that not all of them are necessarily going to be useful for your program, or even for any program.

But with knowledge comes power, so enjoy the list for its own sake. :-)

S-1-0	Null Authority	An identifier authority.
S-1-0-0	Nobody	No security principal.
S-1-1	World Authority	An identifier authority.
S-1-1-0	Everyone	A group that includes all users, even anonymous users and guests. Membership is controlled by the operating system. Note By default, the Everyone group no longer includes anonymous users on a computer that is running Windows XP Service Pack 2 (SP2).
S-1-2	Local Authority	An identifier authority.
S-1-3	Creator Authority	An identifier authority.
S-1-3-0	Creator Owner	A placeholder in an inheritable access control entry (ACE). When the ACE is inherited, the system replaces this SID with the SID for the object's creator.
S-1-3-1	Creator Group	A placeholder in an inheritable ACE. When the ACE is inherited, the system replaces this SID with the SID for the primary group of the object's creator. The primary group is used only by the POSIX subsystem.
S-1-3-2	Creator Owner Server	This SID is not used in Windows 2000.
S-1-3-3	Creator Group Server	This SID is not used in Windows 2000.

S-1-5-5-X-Y	Logon Session	A logon session. The X and Y values for these SIDs are different for each session.
S-1-5-6	Service	A group that includes all security principals that have logged on as a service. Membership is controlled by the operating system.
S-1-5-7	Anonymous	A group that includes all users that have logged on anonymously. Membership is controlled by the operating system.

S-1-5-9	Enterprise Domain Controllers	A group that includes all domain controllers in a forest that uses an Active Directory directory service. Membership is controlled by the operating system.
S-1-5-10	Principal Self	A placeholder in an inheritable ACE on an account object or group object in Active Directory. When the ACE is inherited, the system replaces this SID with the SID for the security principal who holds the account.
S-1-5-11	Authenticated Users	A group that includes all users whose identities were authenticated when they logged on. Membership is controlled by the operating system.

All of these are greate for those LookupAccountSid calls that solve problems previously discussed....

The first number is a user number and the second a group number; then comes a user name, a home directory, and a default shell. The "x" used to be the password field and is now a spacer.
