AD ans home folder access -> admin access denied

[greg]

Hi all,

So here is my access problem, i can't acces to volume C share and home share

user acces works fine, but from domain administrator session can't see user's share

So i try to connect as readynas admin but acces is denied too

Also either with admin or domain\adminsitrator i can browse share : using explorer with \\readynas\ so home and C share are displayed but acces is denied

i try to reinstall firmware and rejoin domain but nothing help

in the smbd.log i see this entry :

[2008/07/08 15:33:58, 2] auth/auth.c:check_ntlm_password(319)
check_ntlm_password: Authentication for user [admin] -> [admin] FAILED with error NT_STATUS_NO_SUCH_USER
[2008/07/08 15:33:58, 2] auth/pampass.c:smb_pam_error_handler(73)
smb_pam_error_handler: PAM: Account Check Failed : User not known to the underlying authentication module

Here is my configuration RAIDiator 4.01c1-p1 [1.00a041] and domain security enabled
domain controller is a windows 2k3 Small business server.

Could it be a bad configuration ?
