wso2 - 将数据库登录更改为 LDAP 后数据接收器出错

问题描述

按照本教程https://docs.wso2.com/display/IS410/Connect%2Bthe%2BWSO2%2BAPI%2BManager%2Bto%2Ban%2BExternal%2BLDAP%2BUser%2BStore 在 WSO2 API Manager 中启用 LDAP 身份验证后，我重新启动服务器并出现此错误：

但是服务器启动正确，我可以使用 LDAP 用户登录。那么，我如何控制该消息或编辑错误中引用的用户/密码，因为我认为这是在检查默认的 wso2 身份验证。

解决方案

This error can happen when using binary data publisher for throttling and the username or password is incorrect. Related configuration is located inside "ThrottlingConfigurations" section of "repository/conf/api-manager.xml" file. Try to update the Username and Password inside the "DataPublisher" configuration to the LDAP user. 

<ThrottlingConfigurations>
    <EnableAdvanceThrottling>true</EnableAdvanceThrottling>
    <DataPublisher>
        <Enabled>true</Enabled>
        <Type>Binary</Type>
        <ReceiverUrlGroup>tcp://${carbon.local.ip}:${receiver.url.port}</ReceiverUrlGroup>
        <AuthUrlGroup>ssl://${carbon.local.ip}:${auth.url.port}</AuthUrlGroup>
        <Username>user_name</Username>
        <Password>password</Password>

  ....
</ThrottlingConfigurations>
