我们无法让Spring Security / Kerberos / AD适用于我们的网络应用。我们的诊断是我们的AD服务器发送一个NTLM令牌(我们可以告诉它以“TlRMTVNT .....”开头)到IE和IE然后将它发送到我们的应用程序并且它失败了。我们的AD服务器应该向IE发送Kerberos / SPNEGO令牌。
“活动部件”如下:
我们已按照此处的说明详细说明了所有内容:

当我们启动TC服务器时,我们可以很好地看到事情初始化(即没有错误 - “从keytab获得的原则密钥”):

准备测试,然后我们在IE中启用了“Windows集成身份验证”,并确保该域名已在IE的本地Intranet站点部分中列出。然后,我们使用完全限定的域名连接到我们的Web应用程序。
当我们这样做时,我们在浏览器中遇到以下错误:
500 Internal server error.

似乎(从我们可以看出)AD服务器向IE和IE发送NTLM令牌(我们可以告诉它以“TlRMTVNT .....”开头)然后将其发送到我们的应用程序并且它失败了。
我们的AD服务器应该向IE发送Kerberos / SPNEGO令牌。
其他说明:
答案 0 :(得分:29)
当您在同一台计算机上运行客户端和服务器时,可能会发生这种情况。当您使用IE与运行tomcat的机器通信时,请确保这些是不同的机器。
此外,您需要确保服务器计算机已加入keytab(testdomain.ourcompany.co.uk)中指定的域,或者您可能会退回到NTLM。即使您的服务器位于未加入域的计算机上,您的密钥表仍然可以正常工作(您将看到您显示的好密钥表解密),但是IE可能会感到困惑,而不是做正确的事情。
AD只是非常喜欢为Server 2003说arcfour-hmac,所以你需要确保在krb5.ini文件中正确设置它。
您可以像这样正确创建密钥表:
C:\>ktpass -princ HTTP/ourweb.testdomain.ourcompany.co.uk@TESTDOMAIN.OURCOMPANY.CO.UK -mapuser ourweb.testdomain.ourcompany.co.uk@TESTDOMAIN.OURCOMPANY.CO.UK -crypto RC4-HMAC-NT -ptype K
RB5_NT_PRINCIPAL -pass * -out ourweb.keytab
Targeting domain controller: test-dc.ourcompany.co.uk
Using legacy password setting method
Successfully mapped HTTP/ourweb.testdomain.ourcompany.co.uk@TESTDOMAIN.OURCOMPANY.CO.UK to ourweb.testdomain.ourcompany.co.uk.
Key created.
Output keytab to ourweb.keytab:
Keytab version: 0x502
keysize 75 HTTP/ourweb.testdomain.ourcompany.co.uk@TESTDOMAIN.OURCOMPANY.CO.UK ptype 1 (KRB5_NT_PRINCIPAL)
vno 3 etype 0x17 (RC4-HMAC) keylength 16 (0x0fd0e500225c4fca9a63a9998b17ca32)
我没有看到你设置了krb5.ini文件。您需要在服务器计算机上正确设置该设置(默认位置C:\ WINDOWS \ krb5.ini):
[domain_realm]
.testdomain.ourcompany.co.uk = TESTDOMAIN.OURCOMPANY.CO.UK
testdomain.ourcompany.co.uk = TESTDOMAIN.OURCOMPANY.CO.UK
[libdefaults]
default_realm = TESTDOMAIN.OURCOMPANY.CO.UK
permitted_enctypes = aes128-cts aes256-cts arcfour-hmac-md5
default_tgs_enctypes = aes128-cts aes256-cts arcfour-hmac-md5
default_tkt_enctypes = aes128-cts aes256-cts arcfour-hmac-md5
[realms]
VERDAD.LOCAL = {
kdc = test-dc.ourcompany.co.uk
admin_server = test-dc.ourcompany.co.uk
default_domain = TESTDOMAIN.OURCOMPANY.CO.UK
}
您可能还需要设置以下属性(如果您尝试从IDE运行此属性):
<systemProperties>
<java.security.krb5.kdc>test-dc.ourcompany.co.uk</java.security.krb5.kdc>
<java.security.krb5.realm>TESTDOMAIN.OURCOMPANY.CO.UK</java.security.krb5.realm>
</systemProperties>
我正在为maven使用org.codehaus.mojo插件,它将这些设置在pom文件中,如下所示:
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>tomcat-maven-plugin</artifactId>
<configuration>
<server>tomcat-development-server</server>
<port>8080</port>
<path>/SecurityTest</path>
<systemProperties>
<java.security.krb5.kdc>test-dc.ourcompany.co.uk</java.security.krb5.kdc
<java.security.krb5.realm>TESTDOMAIN.OURCOMPANY.CO.UK</java.security.krb5.realm>
</systemProperties>
</configuration>
</plugin>
</plugins>
</build>
答案 1 :(得分:7)
我也遇到过这个问题。 对于那些将来会遇到这个问题的不幸的人,这个问题的另一个原因是通过ip访问服务器而不是它的A记录(主机名)
答案 2 :(得分:5)
我也有同样的问题,花了很长时间才找到罪魁祸首。因此,如果您已完成上述所有操作,仍然使用NTLM令牌而不是kerberos。确保你没有重复的SPN。在我的情况下,我有2个帐户映射到相同的SPN,原因是我以前在同一服务器上运行一个单独的Web应用程序,使用不同的服务帐户,但映射到相同的SPN,这是HTTP /
希望有所帮助
