一、ITIL即IT基础架构库(Information Technology Infrastructure Library, ITIL，信息技术基础架构库)由英国政府部门CCTA(Central Computing and Telecommunications Agency)在20世纪80年代末制订，现由英国商务部OGC(Office of Government Commerce)负责管理，主要适用于IT服务管理（ITSM）。ITIL为企业的IT服务管理实践提供了一个客观、严谨、可量化的标准和规范。

二、Django用户自定义认证

1、创建models.py

from django.db import modelsimport hashlib#自己的后台数据库表.accountclass Account(models.Model):username = models.CharField(u"用户名",blank=True,max_length=32)password = models.CharField(u"密码",blank=True,max_length=50)domain = models.CharField(u"可操作域名",blank=True,max_length=256,help_text='填写多个域名，以,号分隔')is_active = models.IntegerField(u"is_active",blank=True)phone = models.CharField(u"电话",max_length=50)mail = models.CharField(u"邮箱",max_length=50) def __unicode__(self):return self.username def is_authenticated(self):return Truedef hashed_password(self, password=None):if not password:return self.passwordelse:return hashlib.md5(password).hexdigest()def check_password(self, password):if self.hashed_password(password) == self.password:#if password == self.password:return Truereturn Falseclass Meta:

db_table = "account"

2、auth.py

rom django.contrib.auth.models import User

from myauth.models import Accountclass MyCustomBackend: def authenticate(self, username=None, password=None):try:user = Account.objects.get(username=username)except Account.DoesNotExist:return Noneelse:if user.check_password(password):try:django_user = User.objects.get(username=user.username)except User.DoesNotExist:#当在django中找不到此用户，便创建这个用户django_user = User(username=user.username,password=user.password)django_user.is_staff = Truedjango_user.save()return django_userelse:return Nonedef get_user(self, user_id):try:return User.objects.get(pk=user_id)except User.DoesNotExist:return None

3、把自己创建的表也加入到进去，admin.py

from myauth.models import Accountfrom django.contrib import admin admin.site.register(Account)


4、在settings.py中添加认证：

AUTHENTICATION_BACKENDS = ('myauth.auth.MyCustomBackend' ,)
