cPanel has released an autorepair script to resolve a problem caused by a CentOS and Red Hat Enterprise Linux security update to sudo.
If you are experiencing problems resolving domains, please take the following action from WHM or a root shell:
To apply the fix from WHM:
==========================
1. Login to WHM as root
2. Manually append the following to the url:
/scripts2/autofixer
examples:
https://[YOURSERVERHERE]:2087/scripts2/autofixer
https://[YOURSERVERHERE]:2087/cpsess999999/scripts2/autofixer
3. In the script name field, enter:
nsswitch
4. Click Submit
To apply the fix from a root shell:
===================================
/scripts/autorepair nsswitch
# or for newer versions of cPanel
/usr/local/cpanel/scripts/autorepair nsswitch
cPanel has assigned internal case number 60611 to track this problem.
At this time, we believe only RHEL 5, and CentOS 5 are affected if /etc/nsswitch.conf contained a sudoers line prior to the sudo rpm being updated.
