Rob, your suspicion was correct the sudoers line was missing.
It actually looks like the ipa-client-automount --uninstall reverts the
nsswitch.conf file to default pre-ipa values.
Still a bit curious that the ipa-client-automount
--location=server_mounts did not take on the ipa-server. If there is a
good reason for this behavior I would suggest that the
ipa-client-automount command would not even start it it was executed on
the ipa server.
I don't understand this paragraph at all. What does "did not take" mean?
What do you mean by the command doesn't start?

thanks everyone!

central sudo on ipa-server
ipa-client-automount --uninstall was(is?) a bit broken in that it tries
to revert back to an older configuration, but it can accidentally revert
it to a state before the ipa-client was installed (as opposed to the
state where automount was installed). Check your nssswitch.conf file and
compare it to other clients on which things work fine. You might notice
differences.

Need help restoring central sudo rights on ipa server.
How I broke it!!!: I decided to take advantage of the centralized
automount feature with a custom location for a couple mounts.
When I ran
the ipa-client-automount --location=server_mounts it appeared to
install
correctly but that didn't appear not to work so my plan was to
manually
setup the automount since it is only one machine. So of course I
ran the
ipa-client-automount --uninstall on the ipa server and thats
when I lost
the sudo rights on the ipa server: superuser not in the sudoers
file,
this incident will be reported.
I have repeated this steps with the same results:
Initially sudo works for superuser
And after ipa-client-automount --location=server_mounts (on the
ipa-server)
sudo still works
but after, ipa-client-automount --uninstall
no sudo for superuser on the ipa server but the superuser still
has sudo
privilages on the clients????
background/versions:
My setup is all CentOS 7.2 machines with one ipa server and the
rest are
clients all using ipa version 4.2.0.
I had no issues using the ipa-client-automount on all my clients to
configure network homes and shares as well as setting up a superuser
with central sudo powers before this happened.
1.) Don't be too harsh if it is a BIG NO-NO to run the
ipa-client-automount command on the ipa-server
2.) Not sure what logs or config files i need to post.
I'd confirm that sssd is still configured to do sudo by looking for
sss in the sudoers line in /etc/nssswitch.conf and ensure that sudo
is an enabled service in /etc/sssd/sssd.conf, probably something like:
services = nss, sudo, pam, ssh
