AD user whose name with space can not see his home dir via windows client on samba-3.5.9

[jinyunshuai]

Hi ,
 
I have a problem:
When I login samba server via windows client with AD user whose name with space
 it can not see his home dir.
if with a AD user whose name  not include space can see his home dir.  
 
my smb.conf  has included following lines:
[homes]
    comment = Home directories
    read only = No
    browseable = No
 
This issue does not exist on samba-3.5.5.

is it an intentional change in samba-3.5.9?

thanks in advance!
