NIS, Tru64, and Linux... again?

hi all,

i'm new to the list, but i promise i've google'd and searched via
tru64.org's various interfaces for this information. i've found
bits and pieces of lore (mostly "don't do it") but i need to ask
since the last firm information was posted in 2001.

the problem is that we have a linux NIS server in a limited network
environment for research, and the Tru64 box just won't allow console
or ssh logins that are from NIS. local logins are fine, and "su -
<nisuser>" works just fine.

i was recently handed this XP1000 workstation running Tru64 ("OSF5.1"
according to uname -a), and asked to make it all work. i've got
solaris and linux admin knowledge, so i'm coming at this blind with
respect to Tru64 specifics. i managed to get the basics configured --
nfs, ethernet, etc, etc. i'm looking for help on what i can try or
what might be wrong. if the bottom line is "get a solaris 2.7 box
to be the NIS server", then that's what i'll have to do... (this
was the result in 2001)

the Tru64 box is running in Basic Security mode. the enhanced
security mode isn't installed from what "setld -i" tells me.

my ssh server (if it matters) is OpenSSH 3.9p1. (since console login
doesn't work, i'm not sure that's relevant.) when i run "sshd -Dde"
to get some debug data on what's failing, it reports:

   Couldn't authenticate <nis-user> to <nis-server>

yet when i do a "ypwhich", i get the <nis-server>, and if do a
"ypcat passwd", i get the exact dump i expect.

checking via "sysman" the chain "Accounts->NIS Users-><random user>",
i see that each NIS account looks just fine. (the account isn't
locked; the home dir, shell, etc all look okay; the UID of 1000 is
okay; the password/confirm fields are of course blank.)

login as any local user, "su - <nis-user>" gives me everything fine.
shell, NFS home dir, permissions, etc, etc.

i'm stumped.

any advice most appreciated. (also is it free to upgrade this thing
to 5.1A or B, and is it worth it regardless of monetary issue?)
please send advice with specific commands or man page pointers -- i'm
new enough to Tru64 to get confused with the various flavor
peculiarities.

thanks,

ps> the linux machine is gentoo, running x86 stable, all current. i
    keep meaning to convert it back to something more sane since it
    became the central server by default, but... no time yet.
