%U vs %u substitutions

Hi,
I was writing up stuff about % substitutions and I noticed something funny.
%U is processed in standard_sub_basic, which does not require a connection
structure. %u is processed by standard_sub, which does require a
connection structure.
However, it seems like there are times when standard_sub_basic will be
called when %U does not yet have a value, ie, when the SessSetup&X has not
yet been processed by smbd.
Hmmm, now I see it a bit better after looking at the code and thinking
about things.
There are three phases, roughly speaking:
>From startup to before the SessSetup&X
>From SessSetup and X to TreeCon
After TreeCon ...
Try the following:
[spec-%u]
It produces interesting results ...
So, I guess the distinction to be made here is that standard_sub_basic
substitutions only do substitutions that make sense in the absence of any
tree connects having been done (which translates into a connection from
Samba's point of view), while standard_sub is called with a connection
structure (ie service) and can make all the substitutions it wants to.
Regards
