The best you will get is the utmp information, as this is more accurate
than the per-share info (due to multiple users of a given share).

I've long proposed to implement 'session exec' scripts for this purpose,
but never got around to it (and I don't do Samba3 any more).

However, if you read the discussion that occurred last year on
'preventing multiple simultaneous logons', you will see why this is so,
so hard to get right.
