Identifying System Users
Identifying System Users
The system user community supported by the operating system is organized into 256
groups, each of which can include 256 individual users for purposes of administration.
(Groups can include more than 256 users for file-sharing purposes.) Each system user
added to a NonStop system is assigned a user ID and a user name.
A user ID is a pair of numbers separated by a comma:
group-num , member-num
A user name is a pair of names separated by a period:
group-name.member-name
In most instances, you can use either a user ID or a user name to identify a user in a
SAFECOM command.
You can also identify users by aliases, which are described in User Aliases on
page 2-19.
User IDs
A user ID consists of an administrative group number and a member number,
separated by a comma.
group-num
is a number in the range 0 through 255. Two group numbers and their associated
group names are defined by default:
group-name group-num
SUPER 255
NULL 0
member-num
is a number in the range 0 through 255. The member-num value 255 is reserved
for group managers. The manager of the super group (255,255) is the local super
ID. Each member number must be unique within its administrative group.
A user’s administrative group is identified by the member-num portion of the user ID.
An example of a user ID is 12,104. The user’s administrative group is group number
12, and the user is member number 104 within the group.
