凭证无法委托 - Alfresco Share

凭证无法委托 - Alfresco Share

我在 Redhat 6 上配置 Alfresco 4.0.d 时遇到了困难。

我正在使用 Kerberos 身份验证,它似乎工作正常,单点登录在主 alfresco 应用程序本身上运行良好。我已经完成了配置步骤以使共享应用程序正常运行,但无论我怎么尝试,每次浏览器访问时,我都会在 catalina.out 中收到此错误http://server:8080/share以及“Windows 安全”密码框。

WARN  [site.servlet.KerberosSessionSetupPrivilegedAction] credentials can not be delegated!

以下是我目前所做的:

使用 AD 用户和计算机,选择帐户alfrescohttp,然后选择“信任此用户委派任何服务(仅限 Kerberos)”。

共享配置-custom.xml

复制/opt/alfresco-4.0.d/tomcat/shared/classes/alfresco/web-extension/share-config-custom.xml.sampleshare-config-custom.xml编辑如下:

   <config evaluator="string-compare" condition="Kerberos" replace="true">
      <kerberos>
         <password>*****</password>
         <realm>MYDOMAIN.CO.UK</realm>
         <endpoint-spn>HTTP/[email protected]</endpoint-spn>
         <config-entry>ShareHTTP</config-entry>
      </kerberos>
   </config>


   <config evaluator="string-compare" condition="Remote">
      <remote>
         <keystore>
             <path>alfresco/web-extension/alfresco-system.p12</path>
             <type>pkcs12</type>
             <password>alfresco-system</password>
         </keystore>

         <connector>
            <id>alfrescoCookie</id>
            <name>Alfresco Connector</name>
            <description>Connects to an Alfresco instance using cookie-based authentication</description>
            <class>org.springframework.extensions.webscripts.connector.AlfrescoConnector</class>
         </connector>

         <endpoint>
            <id>alfresco</id>
            <name>Alfresco - user access</name>
            <description>Access to Alfresco Repository WebScripts that require user authentication</description>
            <connector-id>alfrescoCookie</connector-id>
            <endpoint-url>http://localhost:8080/alfresco/wcs</endpoint-url>
            <identity>user</identity>
            <external-auth>true</external-auth>
         </endpoint>
      </remote>
   </config>

krb5配置文件

/etc/krb5.conf像这样设置文件:

[logging]
default = FILE:/var/log/krb5libs.log
kdc = FILE:/var/log/krb5kdc.log
admin_server = FILE:/var/log/kadmind.log

[libdefaults]
default_realm = MYDOMAIN.CO.UK
default_tkt_enctypes = rc4-hmac
default_tgs_enctypes = rc4-hmac
forwardable = true
proxiable = true

[realms]
MYDOMAIN.CO.UK = {
  kdc = mydc.mydomain.co.uk
  admin_server = mydc.mydomain.co.uk
}

[domain_realm]
.mydc.mydomain.co.uk = MYDOMAIN.CO.UK
mydc.mydomain.co.uk = MYDOMAIN.CO.UK

java.login.config

/opt/alfresco-4.0.d/java/jre/lib/security/java.login.config配置如下:

Alfresco {
   com.sun.security.auth.module.Krb5LoginModule sufficient;
};

AlfrescoCIFS {
   com.sun.security.auth.module.Krb5LoginModule required
   storeKey=true
   useKeyTab=true
   keyTab="/etc/alfrescocifs.keytab"
   principal="cifs/server.mydomain.co.uk";
};

AlfrescoHTTP {
   com.sun.security.auth.module.Krb5LoginModule required
   storeKey=true
   useKeyTab=true
   keyTab="/etc/alfrescohttp.keytab"
   principal="HTTP/server.mydomain.co.uk";
};

com.sun.net.ssl.client {
   com.sun.security.auth.module.Krb5LoginModule sufficient;
};

other {
   com.sun.security.auth.module.Krb5LoginModule sufficient;
};

ShareHTTP {
com.sun.security.auth.module.Krb5LoginModule required
storeKey=true
useKeyTab=true
keyTab="/etc/alfrescohttp.keytab"
principal="HTTP/server.mydomain.co.uk";
};

alfresco-全局配置文件

最后,在alfresco-global.conf

authentication.chain=kerberos1:kerberos,alfrescoNtlm1:alfrescoNtlm

kerberos.authentication.real=MYDOMAIN.CO.UK
kerberos.authentication.user.configEntryName=Alfresco
kerberos.authentication.cifs.configEntryName=AlfrescoCIFS
kerberos.authentication.http.configEntryName=AlfrescoHTTP
kerberos.authentication.cifs.password=******
kerberos.authentication.http.password=*****
kerberos.authentication.defaultAdministratorUserNames=administrator

ntlm.authentication.sso.enabled=true

正如我所说,我遇到了瓶颈,如果您能给我任何帮助,我将不胜感激!这个问题也发布在 Alfresco 论坛上,但我想知道 serverfault 上是否有人遇到过类似的实施挑战?

答案1

从 krb5.conf 中删除以下行可以解决问题。

forwardable = true
proxiable = true
