Ice是个好东西，希望国内能普及
此文介绍如何实现Ice注册中心的账号密码登录。
使用的是 IceGrid.Registry.AdminCryptPasswords 配置项；在icegridregistry对应的配置文件中进行配置。
1、如何配置 AdminCryptPasswords[ice官方文档]
==================================================================
原文：
IceGrid.Registry.AdminCryptPasswords
Synopsis
IceGrid.Registry.AdminCryptPasswords=file
Description
Specifies the file name of an IceGrid registry access control list for administrative clients. Each line of the file must contain a user name and
a password, separated by white space. The password must a MCF encoded string as described here. If this property is not defined, the
default value is admin-passwords. This property is ignored if IceGrid.Registry.AdminPermissionsVerifier is defined.
==================================================================
2、如何生产账号密码
密码是经过hash加密，把密文配置到密码文件中。相同的密码，每次hash得到的密文都不一样。
CentOS版本：2.6.32-754.el6.x86_64
python版本：Python 2.6.6
用户权限：root
安装：pip install zeroc-icehashpassword
生成密文工具：icehashpassword
如何生成加密账号密码：WritingaPasswordFile[ice官方文档]
==================================================================
原文：
On Linux:
CryptusingSHA-256, orSHA-512as the digest algorithm.
The propertyGlacier2.CryptPasswordsspecifies the name of the password file:
Glacier2.CryptPasswords=passwords
The format of the password file is very simple. Each user name-password pair must reside on a separate line, with whitespace separating the user name from the password. For example, the following password file contains an entry for the user nametest:
test $5$rounds=110000$5rM9XIDChkgEu.S3$ov7yip4NOi1wymAZmamEv1uKPQRB0WzasoJsWMpRT19
icehashpasswordHelper Script
You can use theicehashpasswordhelper script to generate these username-password pairs. This script requiresPythonandpipto be installed. To install this script run:
> pip install zeroc-icehashpassword
You can now use the commandicehashpassword:
> icehashpassword
Password:
$5$rounds=110000$5rM9XIDChkgEu.S3$ov7yip4NOi1wymAZmamEv1uKPQRB0WzasoJsWMpRT19
==================================================================
3、配置好password文件，然后重启注册中心，即可实现账号密码登录限制。
注册中心配置文件：
#NullPermissionsVerifier 必须
#IceGridAdmin.Username=foo
#IceGridAdmin.Password=bar
#IceGrid.Registry.AdminPermissionsVerifier=DemoIceGrid/NullPermissionsVerifier
IceGrid.Registry.AdminCryptPasswords=passwords.txt
密码文件 passwords.txt：
名称 + 空格 + 密文
test $6$rounds=656000$lsuADSb779/0eU3L$T4oYilkHZ9LWB2OO4mhp9aeGYgqn2dLY/7HNHFxLJZpjR/ylhLuBI4HfihciYnQ/qd5v.P7ZtW3dOFEYia3AD1
登录时输入账号密码：

成功：进入！
