Does the machine where sudo prints this error belongs to the hostgroup
'servers'? If the answer is *no* then you are hitting 1000389.

Yes, the virtual machine where the sudo internal error occurs is a
member of the hostgroup.  So I guess this is a new error and should be
reported?

FYI Dean reported https://bugzilla.redhat.com/show_bug.cgi?id=1006611

I still think it is the same bug as 1000389, however with slightly different back trace. I'll follow up in BZ.

It needs to be installed separately by installing libsss_sudo package.

Yes, I did find the package and installed it.
