samba4 shared folder path

[oscar wu]

I create a shared folder in my samba4 ADDC.

[test1]
path = /share/test1
invalid users =
read list =
write list = @"UUU\Domain Users",@"UUU\Domain Admins"
valid users = @"UUU\Domain Users",@"UUU\Domain Admins"
browsable = yes
inherit permissions = Yes
inherit owner = Yes
inherit acls = Yes
recycle bin = no

realm = uuu.org
netbios name = TESETDC1

When I logoin UUU\administrator in win7 , I can access sysvol and netlogon
folder by "\\uuu.org\sysvol" and "\\uuu.org\netlogon".

When I access test1  by "\\uuu.org\test1", there is a permission error, I
can not access test1 right but i can access test1 by "\\testdc1.uuu.org
\test1".

Is there any setting for accessing \\$realm\$folder ?
