Description Stephen Gallagher 2011-05-03 11:50:42 EDT

+++ This bug was initially created as a clone of Bug #701700 +++

Description of problem:
The select() call can only handle files descriptors lesser than 1024 safely. If the sssd nss or pam client is called from an application with many open files it may happen that the file descriptor used by the sssd client is large that 1024 which may case undefined and unexpected behaviour.

Version-Release number of selected component (if applicable):
all
