某局点部分访客偶发性认证失败案例

无

现场做访客认证，短信验证自动开户的形式，出现终端偶发性开户失败导致认证失败

通过前台日志（imcforground）中发现如下报错，通过如下报错可以确认是EIA通过restful接口创建访客时接口无法访问。

所以可以确认为接口调用失败，直接通过web界面测试http://ip：端口/imcrs 登录测试，现场因为是偶发性，所以验证接口正常。说明本身接口没有问题否则会一直失败。

通过debug日志分析，调用接口失败的报错为403，原因是：使用不正确的用户名密码连接失败次数过多被禁用一段时间导致。

然后通过接口调用的配置发现WSM组件有调用接口的情况。

 通过配置发现现场WSM中EIA参数配置中勾选了自动从EIA获取终端信息，但是此处密码是错误的。将密码修改正确后解决
