Assigning identifiers for users z/OS UNIX System Services Planning GA32-0884-00 |
|
Assigning the same UID to more than one person is strongly discouraged.
If you assign the same UID to more than one user ID, z/OS UNIX and RACF® treat, in some ways, the users
as if they were a single z/OS UNIX user.
For example:
If you assign users the same UID, you should warn them of the effects. For UID(0), the effects are less significant, because superusers have access to all processes and files and because most BPXPRMxx limits are not enforced against superusers. To assign a non-unique UID, you can use the SHARED keyword of the RACF ADDGROUP or ALTGROUP command if the SHARED.IDS profile is defined in the UNIXPRIV class. |
