UID in the Rhel7-linux

In the RHEL7:

· UID 0 assigned to super users

· UID 1-200 is a series of "system users" that are statically assigned to Red Hat system processes

· UID 201-999 is a series of "system users" that are used by system processes that do not have their own files in the file system. They are typically allocated dynamically from the available pools when they are installed with the software they need. Programs run as these "unprivileged" system users to restrict access to only the resources they need to run properly

· UID 10000+ is a range that is available for distribution to ordinary users

Prior to RHEL7:

· UID 0 assigned to super users

· UID 1-499 User System User

· UID for ordinary users

The default range used by Useradd, Groupadd, can be changed from/etc/login.defs.
