为什么CUPS OpenWRTpipe理页面提示login，添加打印机时不会占用用户/密码？

我使用OpenWRT 14.07，CUPS 1.5.4。 当我尝试添加打印机时，UI会引导我浏览整个工作stream程，直至完成。 在工作stream程结束后，我find了打印机，添加了说明，指定的驱动程序等。点击“添加打印机”。

此时，CUPSpipe理用户界面向我发送一个基本身份validation请求，要求在“CUPS”领域中input用户名和密码：

用户名和密码正在被http://192.168.0.1:631请求。 该网站说：“CUPS”

我无法让pipe理网站接受任何用户名/密码组合。 我曾经在不同的屏幕上看到过这个，并input了“root”/“password”，UI已经接受了。 从那时起，我一直玩这个设置，现在唯一一次提示input用户名和密码的时候是我点击“添加打印机”。

• 在networking上连接HP打印机的简单而优雅的解决scheme
• CUPS打印服务器; 多个目的地
• 打印PDF到打印机（不是“pdf打印机”）
• 杯子不会安装
• SAMBA CUPS三星ML-191x两台打印机精确模型不会区分哪个端口连接

我试图通过直接编辑“printers.conf”（针对build议和绝望）来手动添加打印机。 现在打印机出现了，但作业只是消失了。 （我认为这个build议是有说服力的，而且没有发生一些队列设置步骤）“手动打印机行为可能是一个不同的问题，但是这里适用的观察是”修改打印机“现在具有相同的密码行为。

我对CUPS（在这个级别）和OpenWRT是新手，但是我已经在个人和专业上在PC和embedded式环境中使用了15 – 20年的Linux。

任何帮助表示赞赏。 我的configuration已附加。 我一直在试图解决这个问题一段时间。

这是debugging模式下error_log的尾部
