AD用户登录验证，遍历OU（LDAP）

先安装python-ldap模块

1.验证AD用户登录是否成功

import sqlite3,ldap

domainname='cmr\\'
username='zhangsan'
ldapuser = domainname + username
ldappass='password'
ldappath='ldap://192.168.200.20:389/'
baseDN='OU=ouname,DC=d1,DC=d2,DC=com'

l=ldap.initialize(ldappath)
l.protocol_version = ldap.VERSION3
try:
    l.simple_bind_s(ldapuser,ldappass)
    #print l.simple_bind_s(ldapuser,ldappass)
except Exception,err:  #ldap.LDAPError
    print err.message['desc'] #DC无法连通，或凭据错误，报错也不同

2.验证用户queryusername是否存在

import ldap
domainname='dname\\'
username='authname'
queryusername ='queryusername'
ldapuser = domainname + username
ldappass='password'
ldappath='ldap://192.168.200.20:389/'
baseDN='OU=拍,DC=d1,DC=d2,DC=com'

try:
    l = ldap.initialize(ldappath)
    l.protocol_version = ldap.VERSION3
    #l.simple_bind(ldapuser,ldappass)
    l.bind_s(ldapuser,ldappass)
    searchScope  = ldap.SCOPE_SUBTREE
    searchFiltername = "sAMAccountName" #通过samaccountname查找用户
    retrieveAttributes = None
    searchFilter = '(' + searchFiltername + "=" + queryusername +')'  #searchFilter = '(' + searchFiltername + "=" + username +'*)' 加星号表示模糊查找
    ldap_result =l.search_s(baseDN, searchScope, searchFilter, retrieveAttributes) #返回结果为list或None
    #searchFilter =  '(&(objectClass=person)(sAMAccountName=username))'
    #ldap_result =l.search(baseDN, searchScope, searchFilter, retrieveAttributes)
    #ldap_result =l.search_ext_s(baseDN, searchScope, searchFilter, retrieveAttributes)
    #print ldap_result
    if len(ldap_result) == 0:
        print queryusername + ' Doesnot Exist'
except ldap.LDAPError, e:
    print e
finally:
    l.unbind_s() #解除ldap binding
    del l

 3.遍历某个OU下所有用户

# -*- coding: UTF-8 -*-

import ldap
domainname='umr\\'
username='authusername'
ldapuser = domainname + username
ldappass='password'
ldappath='ldap://192.168.200.20:389/'
baseDN='OU=ServerAdmin,DC=umr,DC=uu,DC=com'

try:
    l = ldap.initialize(ldappath)
    l.protocol_version = ldap.VERSION3
    #l.simple_bind(ldapuser,ldappass)
    l.bind_s(ldapuser,ldappass)
    searchScope  = ldap.SCOPE_SUBTREE
    retrieveAttributes = None
    searchFilter = '(&(objectClass=person))' #遍历该OU下所有用户，包含子OU
    ldap_result =l.search_s(baseDN, searchScope, searchFilter, retrieveAttributes) #返回结果为list或None

    for pinfor in ldap_result:
        #pinfor是一个tuple，第一个元素是该用户的CN，第二个元素是一个dict，包含有用户的所有属性
        if pinfor[1]:
            p=pinfor[1]
            sAMAccountName = p['sAMAccountName'][0] #返回值是一个list
            displayName = p['displayName'][0]
            #如果用户的某个属性为空，则dict中不会包含有相应的key
            if 'department' in p:
                department = p['department'][0]
            else:
                department = None
            print sAMAccountName,displayName,department

    if len(ldap_result) == 0:
        print queryusername + ' Doesnot Exist'
except ldap.LDAPError, e:
    print e
finally:
    l.unbind_s() #解除ldap binding
    del l
