java - 配置 Activemq Web 控制台以使用 LDAP 进行授权和身份验证

Question

在配置 activemq Web 控制台以使用 ldap 进行身份验证和授权时，出现以下错误。我为此使用免费的在线测试 ldap http://www.forumsys.com/en/tutorials/integration-how-to/ldap/online-ldap-test-server/并得到以下错误:

请参阅我的 jetty.xml 和 login.conf 配置部分并提出建议。

登录配置

Answer 1

java.lang.AbstractMethodError 表示正在调用抽象方法。可能是Jetty的JAAS模块没有启用；这意味着 JAAS 相关的 jar 在类路径中不可用。请查看以下链接中有关启用 JAAS 模块的步骤 3。
