Instead of what? RADIUS? TACACS+? or the means of an authenticator
communicating with its client?

I'm not talking about just authentication now. RADIUS et al, eventually
return a simple PASS/FAIL indicator so that bit could easily be handled
by the exit status of an authenticator. Its the essentially arbitrary
attribute=value pairs that can accompany the response that are interesting.
You could of course save the av pairs in a file, and have the client
process read that or use any other IPC mechanism, but storing everything
in the kernel isn't necessary or necessarily desirable.
