samba - Aug 2012 - access my created share in smb.conf Only by Ip

Hello

samba4 beta5
*s4-ad -> samba server Host name
test.s4.com -> domain name*
*Dns Server -> Samba Internal DNS server , Bind 9.9.1-P2*
win xp

have access to default  share such as sysvol  by dns name (\\test.s4.com
\sysvol)

but if  created a share in smb.conf  Only access by IP such as :

\\test.s4.com\myshare   ->  no  access !
\\192.168.1.6\myshare  ->  access

If using *s4-ad.test.s4.com* my share accessible !!!

\\test.s4.com\myshare   ->  no  access !
\\*s4-ad*.s4.com <http://test.s4.com>\myshare   ->  access !

\\test.s4.com\sysvol   ->  access !
\\*s4-ad* <http://test.s4.com>.
<http://test.s4.com>test.s4.com\sysvol  ->
access !

Note:
In *\\test.s4.com* seen all the shared directory, but not accessible

in *samba alpha17* no need type *s4-ad*

what happened ?

This is  Bug in samba4 beta 5 ?


Thanks
