Recently, I updated my server to CentOS 6.5 X64 version
I configured the machine usual
> yum install samba
I found out the samba service is ok from centos(server) to centos(client), but CentOS(server) <-> Win7(client) failed.
I can login and see files, but I can't copy files to the folder or edit it.
The root cause is that the protocol is changed by microsoft.
If you have the same question, do the following steps. It works for me.
Nothing is guaranteed.
> yum remove 'samba*'
> yum install samba4* krb5* -y
and according to the following setup
cp /etc/samba/smb.conf /etc/samba/smb.conf.bak //備份一下samba的配置文件，
vim /etc/samba/smb.conf
下面綠色字體为原有的，粟色字體的为增加的，藍色字體为修改的

配置完後通過testparm來檢查
說明一點：
samba3.x的早期版本默認使用tdb庫也就是smb.conf默認設定为passdb backend = tdbsam，只需要注釋掉該行添加smb passwd file = /etec/samba/smbpasswd即可使用smbpasswd存儲加密密鑰。從samba3.5.6開始samba規範了passdb backend参數的使用，取消了smb passwd file設定，如果簡單注釋掉passdb backend参數，密鑰文件也不會被存儲到smbpasswd。所以很多人說怎麼修改smb.conf的配置，smbpasswd文件都無法生成，就算手工創建，內容也是0字節。要用傳統的文本方式存儲只需這样設定passdb backend = smbpasswd:/etc/samba/smbpasswd（後面跟的是絕對路徑）>，不要再寫smb passwd file = /etc/samba/smbpasswd，該参數已經不适用於新版本的samba了。
启動smb及nmb服務
service smb start
service nmb start
nmb 是Samba 的主要启動服務器，讓其它機器能知道此機器共享了什麼；如果不打開nmb服務器的話，只能通過IP來訪問
注意：在Samba服務器運行其間，更改了配置最好用service smb reload命令，不要用restart，這样可以防止用戶在連接的過程中被中斷
將smb與nmb加入启動服務
chkconfig --level 35 smb on
chkconfig --level 35 nmb on
查看端口
netstat -antup |grep smb
netstat -antup |grep nmb
第五步：設置用戶
smbpasswd -a itadmin
New SMB password:
Retype new SMB password:
Added user itadmin.
注：如果想要讓/etc/samba/sabpasswd生效，要先启動samba，不然還是以默認的tdbsam方式來記錄密碼
刪除用戶：smbpasswd -x username
更改用戶密碼：smbpasswd username
