Just jumping in, from following the discussion...

So store the public key as an attribute in the LDAP database?

you can use libnss-ldap to have a dynamic user table pulled from LDAP, if that's what you want.  You don't need to touch any local file on the host if you just want to look up your users over the network.

Or you can write your own name service switch extension that does the same.  for GNU systems, see:
