NIS+ and subdomains

We're trying to integrate some Linux boxen into
a NIS+ subdomain here in the UK. The subdomain
is served by servers here in the UK. The domain
is in the US and is served by servers there.
Before I try to post any detailed information,
I'd like to ask: has anyone succeeded in doing this?
We're finding it to be very slow.
BTW we've looked at the source code for pam_unix2-1.2
and there seems to be a bug in how it calls 'crypt_r'.
(More precisely, how it calls the wrapper 'crypt_rn'.)
It does not zero 'struct crypt_data' variables
allocated off the stack. At least its 'initialized'
member must be cleared according to the info docs
('info libc crypt').
The files affected are: unix_auth.c and
I don't know whether the proper fix is to zero in
the wrapper or the code calling the wrapper,
but zeroing outside seems to work OK in our testing.
