samba - Nov 2012 - What is the difference between %S, %u and %U variables in sbm.comf

Hi list,

Can someone please clarify the difference between variables %S %U %u in
smb.conf?

It is not clearly defined in man smb.conf page (at least for me)

%U - session username (the username that the client wanted, not necessarily the
same as the one they got).
%S - the name of the current service, if any.
%u - username of the current service, if any.

That is "session username", "the name of the current
service" and "username of the current service"?


Thanks.

I think this would be the unix user account the smbd process is
running as.  it isn't the same as the username they login as in all
cases.

this would be the name they logged in as.  In some cases this can be
the machine account name too

this is typically the share name.  it can be IPC too, but unlikely
you'd ever use it in a context where you'd see that
