Hello,
I have set up IPA on a private network and have hit some bumps
configuring sudo access for the clients.
kinit seems to work fine for both client and server, user and root.
When I run sudo on the server I see the following in /var/log/messages:
Oct 17 17:53:52 192-168-0-100 [sssd[krb5_child[29237]]]: Decrypt
integrity check failed
Oct 17 17:53:52 192-168-0-100 [sssd[krb5_child[29237]]]: Decrypt
integrity check failed
Thanks,
Andrew

## /etc/nsswitch.conf on client
#
# An example Name Service Switch config file. This file should be
# sorted with the most-used services at the beginning.
#
# The entry '[NOTFOUND=return]' means that the search for an
# entry should stop if the search in the previous entry turned
# up nothing. Note that if the search failed due to some other reason
# (like no NIS server responding) then the search continues with the
# next entry.
#
# Valid entries include:
#
# nisplus Use NIS+ (NIS version 3)
# nis Use NIS (NIS version 2), also called YP
# dns Use DNS (Domain Name Service)
# files Use the local files
# db Use the local database (.db) files
# compat Use NIS on compat mode
# hesiod Use Hesiod for user lookups
# [NOTFOUND=return] Stop searching if not found so far
#
# To use db, put the "db" in front of "files" for entries
you want to be
# looked up first in the databases
#
# Example:
#passwd: db files nisplus nis
#shadow: db files nisplus nis
#group: db files nisplus nis
passwd: files sss
shadow: files sss
group: files sss
#hosts: db files nisplus nis dns
hosts: files dns
# Example - obey only what nisplus tells us...
#services: nisplus [NOTFOUND=return] files
#networks: nisplus [NOTFOUND=return] files
#protocols: nisplus [NOTFOUND=return] files
