Your sudo rules use host groups.

hostgroups are reason why you need to configure NIS domain name.
hostgroups are also available as netgroups in compat tree and sudo reads
information from netgroups.

I hear you and that is what I expected. However, the actual behavior
seems to have changed with 3.3.4 and now 3.3.5.
[dean@desktop <mailto:dean@desktop> ~]$ domainname --nis
domainname: Local domain name not set
[dean@desktop <mailto:dean@desktop> ~]$ sudo -l
Matching Defaults entries for dean on desktop:
requiretty, env_reset, env_keep="COLORS DISPLAY HOSTNAME
KDEDIR LS_COLORS", env_keep+="MAIL PS1 PS2 QTDIR USERNAME LANG
LC_CTYPE", env_keep+="LC_COLLATE LC_IDENTIFICATION LC_MEASUREMENT
LC_MESSAGES", env_keep+="LC_MONETARY LC_NAME LC_NUMERIC LC_PAPER
LC_TELEPHONE", env_keep+="LC_TIME LC_ALL LANGUAGE LINGUAS
User dean may run the following commands on desktop:
(root : root) NOPASSWD: ALL
[dean@desktop <mailto:dean@desktop> ~]$
I think this is a good thing. I would just like to confirm that this is
the new expected behavior and that I have not done something wrong.
We'd need to see your sudo rules to know for sure.
I don't think anything changed in the IPA code to change this behavior,
but we herd a lot of cats so something in another package may be different.
