Yes, I know... I have a similar setup (same version of samba, same
hardware, same OS but a different windows domain on a different
network) that is working fine.

Yes and yes.  If I didn't have that, I'm not sure how samba could have
joined the domain given my configuration.  (But I don't understand
what is going on under the hood.)

Config files posted below.  But first an exciting hint:

When I try to ssh into the box while samba utilities (like "net ads"
and "wbinfo") are frozen -- the ssh login is also frozen until
everything is released.  Maybe nsswitch I fouled.

root at nickel:~ # cat /etc/resolv.conf
domain mydomain.local

/etc/hosts:               localhost localhost.mydomain.local            nickel.mydomain.local nickel             iron.mydomain.local iron
