samba - Mar 2011 - root preexec script run multiple times

Hi all,

In a normal situation, should I expect a [global] root preexec script to 
be run only ONCE per user logon?

I have set some logging in my root preexec script, and have noticed that 
usually it will be run only once on the share IPC$.
However, SOMETIMES I also see it executed on different (existing) share 
names, or two/three/four times in a row on the same IPC$ share. (with 
only a few seconds in between)

Running multiple copies of the same script messes up my script. :-(

So: I this normal behaviour..?

This is on suse 9 enterprise, samba version 3.0.26a.

Yes, it is normal. The client is free to connect and
disconnect to shares as many times as it chooses. But it
should never happen that from one smbd the script is run
more than once simultaneously.

Ok, thanks for clearing that up so quickly. :-)
