[Samba] Macro expansion in valid users = line?

[Tom Dickson]

Hello,

Is it possible to put %U or %S in the valid users line?

I'm trying:

valid users = %D+%U

for a certain homedir setup (automagically creates if non-existent), but the
level 10 logs show that
it always tries: checking |MIXEDDOMAIN+dl| against |%D+%U|, and does not
expand the macro. This is with Samba-3.0.0rc2 (happens with beta3 also.)

Same thing happens with %U or %S.

It worked in samba 2.2.5

Thank you.
