[Message part 1 (text/plain, inline)]
Apologues I forgot to reply all:
Just in SSH:
setxkbmap -query -v 10
Setting verbose level to 10
locale is C
Trying to load rules file ./rules/base...
Trying to load rules file /usr/share/X11/xkb/rules/base...
Success.
Applied rules from base:
rules:      base
model:      pc105
layout:     us
Trying to build keymap using the following components:
keycodes:   xfree86+aliases(qwerty)
types:      complete
compat:     complete
symbols:    pc+us+inet(pc105)
geometry:   pc(pc105)
rules:      base
model:      pc105
layout:     us

See screen shot for when X2Go then let me log in as NIS user but command just hangs.

As local user in X2Gono issues:
[localguy@sobolev Desktop]$ setxkbmap -query -v 10
Setting verbose level to 10
locale is C
Trying to load rules file ./rules/base...
Trying to load rules file /usr/share/X11/xkb/rules/base...
Success.

Ouch... What does setxkmap -query -v 10 show outside the session and
(if possible) inside the session?

BTW: I don't see why NIS users should make a difference here
BTW2: try to avoid NIS. Today I read RHEL8 will finally drop it.

Well, we have seen this in nxagent and added a check to prevent it:
https://github.com/ArcticaProject/nx-libs/commit/148eda36d486c0af019267a644c08d5e8c2f4f8b

Judging from the bug report you linked this fix is more a workaround for
another problem happening before. Will reopen the nx-libs issue...
