Hi  -  An example of the code (relevant snippet) I use is below - a little
different technique, but maybe it will help you figure it out (disclaimer:
I am by NO means an expert with Python - but I can get by):

import ldap
import sys
import string

if __name__ == "__main__":


    try:
        outfile = open("LDAPOut.txt",'w')
        outfile.write("CN|Created|LastLogin|Login\n")
        con = ldap.initialize("<LDAP Server>")
        con.simple_bind(who="cn=<UserID>,o=<O>", cred="<Password>")

        print "success"

    except:
        print "failure"


    res = con.search_s("ou=<OU>,o=<O>",  ldap.SCOPE_SUBTREE,
'objectClass=user' ,['createTimestamp','lastLoginTime','LoginTime'])

Manipulate the 'res =' statement to get the attributes you want.
