[Samba] check if drive letters are occupied by novell

[Marcus Schopen]

Hi,

I use Samba's root preexec funktionality to create dynamic logon scripts:

root preexec = /usr/local/samba/install/bin/make_logon_script
'%m' '%U' '%a' '%g' '%L

Who do I check in the by make_logon_script generated logon .bat script, 
which is executed on the windows clients, if a drive letters is already 
occupied by novell. The logon.bat script should then select the next 
free drive letter for the samba share. Possible?

Thanks,
Marcus
