[Samba] Samba "%G" replacement not working in "Logon script" ?

[Denis BUCHER]

Dear all, 

I experience now a strange bug with Samba 4.1.11 : 

When I define a fixed-name as logon script in smb.conf, it works : 

logon script = employee.bat 

But if I try either %g.bat or %G.bat, or even "%G.bat", it doesn't work
: 

 	* logon script = %g.bat
 	* logon script = %G.bat
 	* logon script = "%G.bat"

In the logs, there was a message showing that Samba was trying to open
the "%G.bat" file and that the file was not found on the disk. (Of
course)
