Description of problem:
ipa-client-automount saves a second copy of /etc/nsswitch.conf and during
uninstall the original version (before ipa-client-install) without the sss
entries is restored. So, it should be documented that uninstalling automount on
its own is not supported. If you want to remove it you have to unconfigure the
whole client and then call ipa-client-install again.

Version-Release number of selected component (if applicable):
ipa-client-3.0.0-42.el6.x86_64

How reproducible:
Inconsistently

Steps to Reproduce:
1. Install ipa-client
2. Install ipa-client-automount
3. Uninstall ipa-client-automount

Restoring configuration
Unable to find 'admin' user with 'getent passwd admin'!
This may mean that sssd didn't re-start properly after the configuration
changes.
