NCSD caches users as invalid until the cache is cleared

Issue

• when the end users reboot their Linux Workstations or servers, they system will fail to properly authenticate against NIS. Then the users are blocked because the NSCD cache shows them as invalid.

[rakkumar@example ~] $ sudo su - testuser
su: user melicher does not exist

[rakkumar@example ~] $ nscd-clear
