Artifactory OSS：LDAP认证超时错误答案

【问题标题】：Artifactory OSS: LDAP authentication timeout errorsArtifactory OSS：LDAP认证超时错误
【发布时间】：2016-11-16 19:34:50
【问题描述】：

我正在我的公司安装 Artifactory OSS。在我们的测试过程中一切都运行良好，但在生产中我们经常收到 LDAP 身份验证错误。详情如下：

操作系统：CentOS 7
Docker 1.10.1
Artifactory 版本：Docker 容器中的 OSS 4.12.0.1

问题：

Artifactory OSS 每天多次停止使用 LDAP 对用户进行身份验证。同时，相邻容器中的其他服务继续使用同一个 LDAP 服务器正常运行。用户身份验证非常少见，仅用于发布滚动。

我们只找到了一种解决方法：- 重新启动 Artifactory 容器。

问题期间日志中出现的错误是：

【解决方案1】：

首先，重要的是要提一下，为了提高搜索性能，您的 Artifactory LDAP“搜索库”字段应尽可能窄，并指向包含您所有需求（用户、组.. .)，但仍然没有强制 Artifactory 搜索整个树（这可能非常重）。关于超时，您可以通过修改 $ARTIFACTORY_HOME/etc/artifactory.system.properties 文件中的 'artifactory.security.ldap.socket.timeoutMillis' 标志来增加默认超时值。您可能还会发现池超时 (artifactory.security.ldap.pool.timeoutMillis) 对于超时空闲连接和清理陈旧连接也很有用。
