Fixed In Version: ipa-3.0.0-43.el6 Doc Type: Bug Fix
Doc Text:
If ipa-client-install updated or created the /etc/nsswitch.conf file, the sudo utility could terminate unexpectedly with a segmentation fault. With this update, ipa-client-install puts a new line character at the end of nsswitch.conf if it modifies the last line of the file. Now, sudo works as expected in this situation.

Yes, this is a valid bug. Is a fix in RHEL-6.7 sufficient for the customer?
