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

Louis, I agree with you, with some exceptions:

You probably mean 'logon', right?

I actually see a problem here, as we have linux member servers, where 
users shouldn't be allowed to browse each others files. This linux 
behavior gives me a real headache sometimes. Therefore I use 
username:Domain Admins.

What do you mean by that?

Louis, do you always put the user in the "Unix Attributes" of the Domain 
Users group? Probably that is necessary for group membership to work 
correctly on linux, right? I just recently discovered this tab and was 
wondering about it.

That is not entirely true and applys to Rowlands last posting as well: 
if you use 'root preexec' in the [homes] section, you can use scripted 
auto-creation of user home share. I just successfully tried this and it 
confirms my reading of the man pages that only if a share is requested 
that is not actually existing, the [homes] section applies and 'root 
preexec' there is executed (in case username exists and password is 
correct).

However, I wouldn't want to use \\server\%username% as home dir 
location, was well.
