<span>此类用于保护Kerberos服务和访问这些服务所必需的凭据。</span>
|
||
<span>服务主体和访问服务所必需的凭据有一对一的映射。</span>
|
||
<span>因此，授予对服务主体的访问权隐含地授予对与服务主体建立安全上下文所必需的凭证的访问。</span>
|
||
<span>无论凭据是在缓存中还是通过与KDC的交换获取，这都适用。</span>
|
||
<span>凭证可以是从钥匙表中获得票证，服务票或秘密密钥。</span>
|
||
<p> <span>ServicePermission包含一个服务主体名称和一个操作列表，该列表指定凭证可以在其中使用的上下文。</span> </p>
|
||
<p> <span>服务主体名是的规范名称<code>KereberosPrincipal</code>供应服务，即KerberosPrincipal表示Kerberos服务主体。</span> <span>该名称以区分大小写的方式处理。</span> <span>本身可能出现星号，表示任何服务主体。</span> </p>
|
||
<p> <span>授予此权限意味着呼叫者可以在动作指定的上下文中使用缓存凭据（TGT，服务票或秘密密钥）。</span> <span>在TGT的情况下，授予该权限也意味着可以通过认证服务交换获得TGT。</span> </p>
|
||
<p> <span>可能的行动是：</span> </p>
|
||
<pre> <span>initiate - allow the caller to use the credential to
|
||
initiate a security context with a service
|
||
principal.
|
||
|
||
accept - allow the caller to use the credential to
|
||
accept security context as a particular
|
||
principal.</span> </pre>
|
||
<span>例如，要指定访问TGT以启动安全上下文的权限，则权限的构建如下：</span>
|
||
<pre> <span>ServicePermission("krbtgt/EXAMPLE.COM@EXAMPLE.COM", "initiate");</span> </pre>
|
||
<p> <span>要获得使用“主机”服务启动上下文的服务票据，该权限的构造如下：</span> </p>
|
||
<pre> <span>ServicePermission("host/foo.example.com@EXAMPLE.COM", "initiate");</span> </pre>
|
||
<p> <span>对于Kerberized服务器，该操作是“accept”。</span> <span>例如，访问和使用Kerberized“主机”服务（telnet等）的密钥所需的权限将被构建如下：</span> </p>
|
||
<pre> <span>ServicePermission("host/foo.example.com@EXAMPLE.COM", "accept");</span> </pre>
