Alan & Martin,
Thanks for the feedback and suggestions. Kodos is a great tool. I use it
regularly to debug my regex mistakes. It can also be a excellent learning
tool to those unfamiliar with regular expressions. Thanks for the
Python-LDAP link and ldif example code.

Ah, ldap...

Honestly, I'm not very good with regular expressions -- and try to avoid
them when possible. But in cases where they seem to be the best option,
I have formed a heavy dependence on regex debuggers like kodos.

Kodos is an excellent regex tool. I use it regularly to verify regex
strings.
Anyways, any suggestions to fix the below code?

Have you had a look at the python-ldap package?

Thanks. I checked the Python module index page and
You could probably access ldap directly with python, if that's an
option. Or, you could roll your own ldif parser (but make sure your data
contains a newline between each dn, or the parser will choke with a
'ValueError: Two lines starting with dn: in one record.'):
import ldif
from cStringIO import StringIO
class MyLDIF(ldif.LDIFParser):
def __init__(self, inputfile):
ldif.LDIFParser.__init__(self, inputfile)
self.users = []
def handle(self, dn, entry):
self.users.append((entry['uid'], entry['cn']))
raw = """\
<snip your ldif example with newlines added between dns>
"""
if __name__ == '__main__':
io = StringIO(raw)
lp = MyLDIF(io)
lp.parse()
for user in lp.users:
uid = user[0][0]
cn = user[1][0]
print uid
print cn
... or ...
You could also use ldif.LDIFRecordList directly without creating a
custom parser class which would return a list of (dn, entry) tuples. The
module author warns that 'It can be a memory hog!', and I can imagine
this is true if you are working with a particularly large ldap directory.
io = StringIO(raw)
directory = ldif.LDIFRecordList(io)
directory.parse()
for dn, entry in directory.all_records:
print entry['uid'][0]
print entry['cn'][0]
