The best you can do is create a NIS map for user_attr, and then set that in all the nsswitch.conf files for each host (NB. it's not listed at all by default, even though prof_attr and auth_attr are.)
(It shouldn't take you much thought to realise why putting it in NIS is a bad idea, but I'm guessing that you're a die-hard NIS shop and so you are already aware of the security risks with doing anything involving NIS.
For any others reading this, if you put it in your LDAP tree and authenticate the name services with SSL certificates then it's rather safer.)
