No, you are not being helpful, try reading the smb.conf manpage, where
you will find this:
log file (G)
This option allows you to override the name of the Samba log
file
(also known as the debug file).
This option takes the standard substitutions, allowing you
to have
separate log files for each user or machine.
No default
Example: log file = /usr/local/samba/var/log.%m
As you can see, there is (as I said) no default and the example clearly
shows that '%m' is expected to work.
Now what could be happening is that the OP is running Samba as a DC and
has somehow started nmbd as well (a lot of the variable substitutions do
not work on a DC), though I think this is unlikely.
If the OP is running a standalone server (much more likely), it should
work. If it isn't working, then it it is likely to be a bug.
