jcifs的NTLMHTTP验证及所犯错误

一、错误提示：0xC0000022: jcifs.smb.SmbAuthException: Access is denied

The NTLM HTTP SSO Filter that used to be included withJCIFS cannot support NTLMv2.

   1) jcifs.smb.lmCompatibility = 0 or 1: SendLM and NTLM
    2) jcifs.smb.lmCompatibility = 2: Send NTLM in both fields
    3) jcifs.smb.lmCompatibility = 3, 4, or 5: Send just LMv2

1、使用包：jcifs-1.3.14.jar

2、Eclipse的web工程中的web.xml配置：下面黑体配置，解决了错误。

3、说明

http://lists.samba.org/archive/jcifs/2004-February/003069.html

http://www.ioplex.com/d/jespa/api/jespa/ntlm/NtlmSecurityProvider.html

二、错误提示：jcifs.smb.SmbException: NTLMv2 requires extendedsecurity (jcifs.smb.client.useExtendedSecurity must be true ifjcifs.smb.lmCompatibility >= 3)  

如果已经增加了上面黑体部分，则需重启tomcat服务器。

三、调试java web程序，时替换jar包，旧jar包修改名称后继续保存在\WebContent\WEB-INF\lib文件夹下，加载旧包，而没有重新加载新包。
