weblogic9.2 SAML 测试遇到的问题

[@more@]

1>我按照OTN官方文档实验在windows环境下测试weblogic9.2 SAML,在XP个人笔记本环境创建domainA,和domainB域
2>开启两个WAR包也成功
3>在http://localhost:7001/appA/login.jsp输入用户名与密码没问题，但在切换到http://localhost:7003/appB/admin/services.jsp
时提示
Error 401--Unauthorized
From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:
10.4.2 401 Unauthorized
The request requires user authentication. The response MUST include a WWW-Authenticate header field (section 14.46)
containing a challenge applicable to the requested resource. The client MAY repeat the request with a suitable Authorization header field
(section 14.8). If the request already included Authorization credentials, then the 401 response indicates that authorization
has been refused for those credentials. If the 401 response contains the same challenge as the prior response,
and the user agent has already attempted authentication at least once, then the user SHOULD be presented the entity that was given in
the response, since that entity MAY include relevant diagnostic information. HTTP access authentication is explained in section 11.
