Gentooboxでsamba4.1共有にアクセスできない

私はWindows 7 x64 PCとGentoo Box（NASとして機能します）を持っています。 Samba3からSamba4.1.6に移行しようとしていますが、Sambaが起動すると接続できません（Samba 3で動作します）。

理解できないかもしれませんが、AD、LDAPなしでSambaを設定し、パスワード情報だけに基づいてWindowsユーザーをLinuxユーザーとして受け入れることはまだ可能ですか？

私の設定は次のとおりです。

[global]
        workgroup = WHITE_SPACE
        server string = WHITE SPACE
        map to guest = Bad User
        obey pam restrictions = Yes
        guest account = smbconsu
        username map = /etc/samba/users.map
        log file = /var/log/samba/samba.log
        max log size = 1000
        load printers = No
        dns proxy = No
        idmap config * : backend = tdb
        hosts allow = 192.168.113., 127.0.0.1
        hosts deny = ALL
        log level=3
[animes]
        comment = Animes Repository
        path = /mnt/raid5/samba/animes
        valid users = +smbshare
        write list = GentooUser
        guest ok = Yes
        case sensitive = No

とusers.map：

GentooUser = "WindowsHost/WindowsUser" "WindowsUser"
smbconsu = guest pcguest smbguest
