[Samba] Can't get 'root preexec' to run

[Ole Traupe]

Rowland, what are [homes] shares on a Unix machine?

What you describe seems to be mostly correct. However, in my eyes there 
is no such thing as a collection of [homes] shares. This section gets 
invoked whenever a non-existing share is requested. Thats what the man 
pages say (with many complicated words) and what I just confirmed here. 
It even works, if you put \\servername\%username% as home path in the 
"Profiles" tab of the ADUC (applies right when you click ok).

Especially, if you are connecting from Windows to 
\\servername\home\%username%, this path *is* honoured and Unix 
Attributes don't come into play. Further, making this Windows way a bit 
paradox or unsuited: if \\servername\home exists, the [homes] section 
won't ever be used. So in my case, I can't create a zfs data set on an 
existing share via 'root preexec', what really annoys me (maybe I put it 
into the netlogon section). It would only apply, if the Samba server 
'servername' is reachable and working correctly, but a [home] (without 
s) share is nonexistent.

(Maybe this is different with different versions of Samba, I don't know.)

But, of course, you are right that on linux the file system has to be 
mounted locally in order to access it. I sometimes forget to mention 
Windows and Linux cases separately.
