I forgot to ask which version of samba your now running, but
assuming it is something around '3.0.25', then here is my
suggestion config. If it is an earlier version let me know.

I believe for an AD domain, if you set the password server
equal to the local domain name it will round-robin query
the closest domain controller. Test it out, it will eliminate
the single point of failure if it works in your environment.

I tend to use tdb for my passwd backend, especially if the number
of users is large, tdb can speed lookups tremendously.

I see no idmap entries here, and don't understand how winbind
is working at all without them, maybe some old compatibility feature...
I suggest, and of course I don't know your full topology, so it
will most definitely need adjusting:
idmap domains = default NA
idmap config default:default = yes
idmap config NA:backend = rid
idmap config NA:range = 16777216 - 33554431
Is that id range valid? I have never used anything over 999999, it
seems very oddly arbitrary, but I suppose you have a reason...
Normally I allocate a 100000 id range per domain, so NA would have
range 100000 - 199999, domain NA2 would have 200000 - 299999 and
so on, makes it easier to determine the RID if the base of the
range is on a power of ten and if you have multiple domains.
idmap alloc backend = tdb
idmap uid = 90000 - 99999
idmap gid = 90000 - 99999
This section here is for local mappings, BUILTINs and such, I
set it as the default, but I'm sure other people will have
their preferences or recommendations.

Notice I removed these lines:

This is old depreciated syntax, the syntax is now 'idmap uid',
and it applies to id domains not explicitly configured with
the 'id config' directive.
Let me know if that helps.
