用Python的python-ldap模块操作openldap目录服务器的示例代码

下面是搜索目录项的代码
#!/usr/bin/python
#-*- coding:utf-8 -*- #设置源码文件编码为utf-8

import ldap

try:
conn = ldap.open("server_name") #server_name为ldap服务器名
conn.protocol_version = ldap.VERSION3 #设置ldap协议版本
username = "cn=admin,dc=company,dc=com" #用户名
password = "123" #访问密码
conn.simple_bind(username,password) #连接

except ldap.LDAPError, e: #捕获出错信息
print e

baseDN = "dc=employees,dc=company,dc=com" #设置目录的搜索路径起点
searchScope = ldap.SCOPE_SUBTREE #设置可搜索子路径

retrieveAttributes = None #None表示搜索所有属性，['cn']表示只搜索cn属性
searchFilter = "cn=test" #设置过滤属性，这里只显示cn=test的信息

try:
ldap_result_id = conn.search(baseDN,searchScope,searchFilter,retrieveAttributes)
#调用search方法返回结果id
result_set = []
while 1:
result_type, result_data = conn.result(ldap_result_id, 0) #通过结果id返回信息
if result_data == []:
break
else:
if result_type == ldap.RES_SEARCH_ENTRY:
result_set.append(result_data)

print result_set[0][0][1]['o'][0] #result_set是一个复合列表，需通过索引返回组织单元(o)信息

except ldap.LDAPError, e:
print e

这里采用的是非同步方式，同步方式的连接和搜索命令后有“_s”后缀，如search_s。非同步方式需通过一个结果id来访问目录服务信息。

 

 

下面是一个修改目录信息的示例：

#!/usr/bin/python
# -*- coding:utf-8 -*-
import ldap

try:
conn = ldap.open("server_name")
conn.protocol_version = ldap.VERSION3
username = "cn=admin,dc=company,dc=com"
password = "123"
conn.simple_bind_s(username,password)

except ldap.LDAPError, e:
print e

try:
dn = "cn=test,dc=employees,dc=company,dc=com"
conn.modify_s(dn,[(ldap.MOD_ADD,'mail','test@163.com')]) #增加一个mail属性
except ldap.LDAPError, e:
print e

ldap.MOD_ADD表示增加属性，ldap.MOD_DELETE表示删除属性，ldap.MOD_REPLACE表示修改属性。

 

 

下面是一个增加目录项的示例：

#!/usr/bin/python
# -*- coding:utf-8 -*-
import ldap,ldap.modlist #ldap.modlist是ldap的子模块，用于格式化目录服务的数据项

try:
conn = ldap.open("server_name")
conn.protocol_version = ldap.VERSION3
username = "cn=admin,dc=company,dc=com"
password = "123"
conn.simple_bind_s(username,password)

except ldap.LDAPError, e:
print e

try:
dn = "cn=test,dc=card,dc=company,dc=com"
modlist = ldap.modlist.addModlist({ #格式化目录项，除对象类型要求必填项外，
'cn': ['test'], #其它项可自由增减
'objectClass': ['top', 'person', 'organizationalPerson', 'inetOrgPerson'],
'o': ['\xe5\xb9\xbf\xe5\xb7\x9e'], #这些为utf-8编码的中文
'street': ['\xe5\xb9\xbf\xe5\xb7\x9e'],
'sn': ['tester'],
'mail': ['test@163.com', 'test@21cn.com'],
'homePhone': ['xxxxxxxx'], 'uid': ['test'] })
# print modlist #显示格式化数据项，格式化后是一个元组列表
conn.add_s(dn,modlist) #调用add_s方法添加目录项

except ldap.LDAPError, e:
print e

其实我们也可按格式化后元组列表的形式把目录项直接写到add_s()里，省却转换的步骤。

下面是删除目录项的示例：
#!/usr/bin/python
# -*- coding:utf-8 -*-
import ldap

try:
conn = ldap.open("server_name")
conn.protocol_version = ldap.VERSION3
username = "cn=admin,dc=test,dc=com"
password = "password"
conn.simple_bind_s(username,password)

except ldap.LDAPError, e:
print e

try:
dn = "cn=sale,dc=test,dc=com"
conn.delete_s(dn)

except ldap.LDAPError, e:
print e

Binding to LDAP Server

Simple Authentication

import ldap
try:
	l = ldap.open("127.0.0.1")
	
	# you should  set this to ldap.VERSION2 if you're using a v2 directory
	l.protocol_version = ldap.VERSION3	
	# Pass in a valid username and password to get 
	# privileged directory access.
	# If you leave them as empty strings or pass an invalid value
	# you will still bind to the server but with limited privileges.
	
	username = "cn=Manager, o=anydomain.com"
	password  = "secret"
	
	# Any errors will throw an ldap.LDAPError exception 
	# or related exception so you can ignore the result
	l.simple_bind(username, password)
except ldap.LDAPError, e:
	print e
	# handle error however you like
	
							

---

Adding entries to an LDAP Directory

Synchrounous add

# import needed modules
import ldap
import ldap.modlist as modlist

# Open a connection
l = ldap.initialize("ldaps://localhost.localdomain:636/")

# Bind/authenticate with a user with apropriate rights to add objects
l.simple_bind_s("cn=manager,dc=example,dc=com","secret")

# The dn of our new entry/object
dn="cn=replica,dc=example,dc=com" 

# A dict to help build the "body" of the object
attrs = {}
attrs['objectclass'] = ['top','organizationalRole','simpleSecurityObject']
attrs['cn'] = 'replica'
attrs['userPassword'] = 'aDifferentSecret'
attrs['description'] = 'User object for replication using slurpd'

# Convert our dict to nice syntax for the add-function using modlist-module
ldif = modlist.addModlist(attrs)

# Do the actual synchronous add-operation to the ldapserver
l.add_s(dn,ldif)

# Its nice to the server to disconnect and free resources when done
l.unbind_s()

                            

Modify entries in an LDAP Directory

Synchrounous modify

# import needed modules
import ldap
import ldap.modlist as modlist

# Open a connection
l = ldap.initialize("ldaps://localhost.localdomain:636/")

# Bind/authenticate with a user with apropriate rights to add objects
l.simple_bind_s("cn=manager,dc=example,dc=com","secret")

# The dn of our existing entry/object
dn="cn=replica,dc=example,dc=com" 

# Some place-holders for old and new values
old = {'description':'User object for replication using slurpd'}
new = {'description':'Bind object used for replication using slurpd'}

# Convert place-holders for modify-operation using modlist-module
ldif = modlist.modifyModlist(old,new)

# Do the actual modification 
l.modify_s(dn,ldif)

# Its nice to the server to disconnect and free resources when done
l.unbind_s()
                            

Searching an LDAP Directory

Asynchronous Search

import ldap

## first you must open a connection to the server
try:
	l = ldap.open("127.0.0.1")
	## searching doesn't require a bind in LDAP V3.  If you're using LDAP v2, set the next line appropriately
	## and do a bind as shown in the above example.
	# you can also set this to ldap.VERSION2 if you're using a v2 directory
	# you should  set the next option to ldap.VERSION2 if you're using a v2 directory
	l.protocol_version = ldap.VERSION3	
except ldap.LDAPError, e:
	print e
	# handle error however you like


## The next lines will also need to be changed to support your search requirements and directory
baseDN = "ou=Customers, ou=Sales, o=anydomain.com"
searchScope = ldap.SCOPE_SUBTREE
## retrieve all attributes - again adjust to your needs - see documentation for more options
retrieveAttributes = None 
searchFilter = "cn=*jack*"

try:
	ldap_result_id = l.search(baseDN, searchScope, searchFilter, retrieveAttributes)
	result_set = []
	while 1:
		result_type, result_data = l.result(ldap_result_id, 0)
		if (result_data == []):
			break
		else:
			## here you don't have to append to a list
			## you could do whatever you want with the individual entry
			## The appending to list is just for illustration. 
			if result_type == ldap.RES_SEARCH_ENTRY:
				result_set.append(result_data)
	print result_set
except ldap.LDAPError, e:
	print e

Deleting an entry from an LDAP Server

Synchronous Delete

import ldap

## first you must bind so we're doing a simple bind first
try:
	l = ldap.open("127.0.0.1")
	
	l.protocol_version = ldap.VERSION3	
	# Pass in a valid username and password to get 
	# privileged directory access.
	# If you leave them as empty strings or pass an invalid value
	# you will still bind to the server but with limited privileges.
	
	username = "cn=Manager, o=anydomain.com"
	password  = "secret"
	
	# Any errors will throw an ldap.LDAPError exception 
	# or related exception so you can ignore the result
	l.simple_bind(username, password)
except ldap.LDAPError, e:
	print e
	# handle error however you like


# The next lines will also need to be changed to support your requirements and directory
deleteDN = "uid=anyuserid, ou=Customers,ou=Sales,o=anydomain.com"
try:
	# you can safely ignore the results returned as an exception 
	# will be raised if the delete doesn't work.
	l.delete_s(deleteDN)
except ldap.LDAPError, e:
	print e
	## handle error however you like
