Question:

Servers are defaulting to 1 GB for user level file descriptor (FD) limits.

How can the custom FD (file descriptor) limits for users be enforced or set without manually editing the /etc/security/limits.conf on each server?

Answer:

The limits.conf can be pushed out with a computer group policy:

1. Create a computer group policy at:

Computer Configuration -> Centrify Settings -> Common UNIX Settings -> Copy Files

a) Set limits.conf as Filename

b) Copy the custom limits.conf to \\yourDomain\SYSVOL\yourdomain\

c) Set /etc/security/ as the Destination

d) Set permissions to 0644, File UID to 0, and Owner UID to 0

2. Log onto the Linux host as root, run the command below and logout:

adgpupdate -T computer

3. Log on as an AD user in the same Linux host and the ulimit setting would be affected on a per user basis.

4. Turn off the GP setting once pushed, otherwise it will run every 90 minutes.
