/etc/security/.ids File

Purpose

Contains standard and administrative user IDs and group IDs.

Description

The /etc/security/.ids file keeps a count so that every UID (userid) and GID (groupid) has it's own unique number. It is not recommended that you edit this file unless it is absolutely necessary.

Example

7 201 11 200

The first number in the example (7) will be the User ID of the next administrative user created on the system. The second number (201) will be the User ID of the next regular user created on the system. The third number (11) is the next administrative Group ID (GID) that will be used when an administrative user is created on the system. The fourth number (200) is the next regular user GID used when a user is created.
