Remarks

If you are calling the NetGroupGetUsers function or the NetGroupSetUsers function, the grui1_name member contains the name of a user that is a member of the specified group.

If you are calling the NetUserGetGroups function or the NetUserSetGroups function, the grui1_name member contains the name of a global group to which the specified user belongs.

User account names are limited to 20 characters and group names are limited to 256 characters. In addition, account names cannot be terminated by a period and they cannot include commas or any of the following printable characters: ", /, , [, ], :, |, <, >, +, =, ;, ?, *. Names also cannot include characters in the range 1-31, which are nonprintable.

Windows Vista and later include an addition to the access control security mechanism of Windows that labels processes and other securable objects with an integrity level. Internet-facing programs are at higher risk for exploits than other programs because they download untrustworthy content from unknown sources. Running these programs with fewer permissions, or at a lower integrity level, than other programs reduces the ability of an exploit to modify the system or harm user data files. The SE_GROUP_INTEGRITY and SE_GROUP_INTEGRITY_ENABLED attributes of the grui1_attributes member are used for this purpose.
