[Samba] kixtart and group based logins

[Barry Smoke]

I know this has been beaten to death, and the solution has always been
pre-exec scripts, 
but I would like to delve further into discssion on group based actions
in log in scripts.

We have been playing with kixtart here, and are very impressed with it's
flexibility. So, here is my primary question...
there is an api that kixtart has that interfaces with the server, so
that group based logins(and other advaced features) can be accomplished.
Has there been any investigations on including this api into the samba
code?

Also, 
samba already supports mapping shares based on someone's group
membership, even if that is not their primary group.

Can this already existing function be used in anyway to allow kixtart to
authenticate based on this?
