ldif LDIF parser and generator

This module parses and generates LDAP data in the format LDIF. It is implemented in pure Python and does not rely on any non-standard modules. Therefore it can be used stand-alone without the rest of the python-ldap package.

Functions

ldif.CreateLDIF(dn, record, base64_attrs=None, cols=76)

Create LDIF single formatted record including trailing empty line. This is a compability function. Use is deprecated!

dn
string-representation of distinguished name
record
Either a dictionary holding the LDAP entry {attrtype:record} or a list with a modify list like for LDAPObject.modify().
base64_attrs
list of attribute types to be base64-encoded in any case
cols
Specifies how many columns a line may have before it’s folded into many lines.
ldif.ParseLDIF(f, ignore_attrs=None, maxentries=0)

Parse LDIF records read from file. This is a compability function. Use is deprecated!

Classes

class ldif.LDIFWriter(output_file, base64_attrs=None, cols=76, line_sep='n')

Write LDIF entry or change records to file object Copy LDIF input to a file output object containing all data retrieved via URLs

class ldif.LDIFParser(input_file, ignored_attr_types=None, max_entries=0, process_url_schemes=None, line_sep='n')

Base class for a LDIF parser. Applications should sub-class this class and override method handle() to implement something meaningful.

Public class attributes:

records_read
Counter for records processed so far
class ldif.LDIFRecordList(input_file, ignored_attr_types=None, max_entries=0, process_url_schemes=None)

Collect all records of LDIF input into a single list. of 2-tuples (dn,entry). It can be a memory hog!

class ldif.LDIFCopy(input_file, output_file, ignored_attr_types=None, max_entries=0, process_url_schemes=None, base64_attrs=None, cols=76, line_sep='n')

Copy LDIF input to LDIF output containing all data retrieved via URLs

Example

The following example demonstrates how to write LDIF output of an LDAP entry with ldif module.

>>> import sys,ldif
>>> entry={'objectClass':['top','person'],'cn':['Michael Stroeder'],'sn':['Stroeder']}
>>> dn='cn=Michael Stroeder,ou=Test'
>>> ldif_writer=ldif.LDIFWriter(sys.stdout)
>>> ldif_writer.unparse(dn,entry)
dn: cn=Michael Stroeder,ou=Test
cn: Michael Stroeder
objectClass: top
objectClass: person
sn: Stroeder

The following example demonstrates how to parse an LDIF file with ldif module, skip some entries and write the result to stdout.

import sys
from ldif import LDIFParser,LDIFWriter

SKIP_DN = ["uid=foo,ou=People,dc=example,dc=com",
   "uid=bar,ou=People,dc=example,dc=com"]

class MyLDIF(LDIFParser):
   def __init__(self,input,output):
      LDIFParser.__init__(self,input)
      self.writer = LDIFWriter(output)

   def handle(self,dn,entry):
      if dn in SKIP_DN:
        return
      self.writer.unparse(dn,entry)

parser = MyLDIF(open("input.ldif", 'rb'), sys.stdout)
parser.parse()
