ldap.ENCODING_ERROR when trying to use SimplePageResultsControl

[Joel Heenan]

I'm trying to use SimplePagedResultsControl so I can pull some data out of Active Directory that has a Server-Limit set. I got most of my code from this guide http://www.novell.com/coolsolutions/tip/18274.html

When I try and run it I get this dump:

"""
SimplePagedResultsControl(1.2.840.113556.1.4.319,True,(10, ''))
Traceback (most recent call last):
  File "./test_ldap_brakeit.py", line 29, in ?
    msgid = l.search_ext(base, ldap.SCOPE_SUBTREE, 'objectclass=user', serverctrls=[lc])

  File "/usr/lib64/python2.4/site-packages/ldap/controls.py", line 78, in encodeControlValue
    return _ldap.encode_page_control(size,cookie)

"""

Server is RHEL5.2 , not too sure about the Active Directory I think it is running on Windows Server 2003.

Here is the code:

#!/usr/bin/python
#

import ldap,ldap.async,pprint
from ldap.controls import SimplePagedResultsControl

server       = 'xxxx.com'
ldap_version = 3
base         = 'dc=example,dc=com'
binddn       = ''
bindpw       = ''
userbase     = ''
port         = 3268
page_size    = 10

l = ldap.open(server,port)
l.protocol_version = ldap_version
l.simple_bind_s(binddn, bindpw)
ldap.set_option(ldap.OPT_REFERRALS, 0)

lc = SimplePagedResultsControl(
        ldap.LDAP_CONTROL_PAGE_OID, True, (page_size,'') )

print lc

msgid = l.search_ext(base, ldap.SCOPE_SUBTREE, 'objectclass=user', serverctrls=[lc])

pages = 0
while True:
        pages += 1
        print "Getting page %d" % (pages,)
        rtype,rdata,rmsgid,serverctrls = l.result3(msgid)
        print "%d results" % len(rdata)
        pctrls = [ c for c in serverctrls if c.controlType == ldap.LDAP_CONTROL_PAGE_OID ]
        if pctrls:
                est, cookie = pctrls[0].controlValue
                if cookie:
                        lc.controlValue = (page_size,cookie)
                        msgid = l.search_ext(base, ldap.SCOPE_SUBTREE, 'objectclass=user', serverctrls=[lc])
                else:
                        break
        else:
                print "Warning: Server ignores RFC 2696 control"
