well it looks nice. has anyone got any favourite bits?
i like the decent methods on LDAPConnection.

I think that if we take the java api, and convert all the Javaisms
to Pythonisms we could even submit "our own" RFC draft. :)

A lot in that java api is 'over the top' in terms of object-orientedness.
Here are some:
=09* do we really need a LDAPDN class? Isn't python's string enough?
=09  (same with LDAPUrl - could be done in the urllib style)
=09* AttributeSet is just a list
=09* can we ignore/hide LDAPExtendedOperation/Response/Listener?

the java api looks overly complex. after whittling it back a bit, i think
a nice pythonesqe api could be developed.

Here's some of the examples converted from Java to API

    #-- Example 9.1
    import LDAP
    ld =3D LDAP.Connection()
    try:
=09ld.connect("localhost", 389)
=09ld.bind("", "")
=09MY_FILTER =3D "sn=3DJensen"
=09MY_SEARCHBASE =3D "o=3DAce Industry, c=3DUS"
=09cons =3D ld.getSearchConstraints()
=09cons.setBatchSize(1)
=09res =3D ld.search(MY_SEARCHBASE, ld.SCOPE_ONE, MY_FILTER, None, 0, cons)
=09for findEntry in res:
=09=09print findEntry.getDN()
=09=09findAttrs =3D findEntry.getAttributeSet()
=09=09enumAttrs =3D findAttrs.getAttributes()
=09=09print "Attributes:"
=09=09for anAttr in enumAttrs:
=09=09=09print `anAttr.getName()`
=09=09=09for aVal in anAttr.getStringValues()
=09=09=09=09print `aVal`
    except LDAP.Exception:
=09print "Error!"
    if ld.isConnected():
=09ld.disconnect()


    #-- example 9.2
    import LDAP

    ld =3D LDAP.Connection()
    try:
=09MY_HOST =3D "localhost"
=09MY_PORT =3D 389
=09ld.connect(MY_HOST, MY_PORT)

=09MY_NAME =3D "cn=3DBarbara Jensen,o=3DAce Industry,c=3DUS"
=09MY_PASSWORD =3D "MysteryLady"
=09ld.bind(MY_NAME, MY_PASSWORD)

=09attrEmail =3D LDAP.Attribute("mail", "ba...@ac...")
=09mod =3D LDAP.Modification(LDAP.REPLACE, attrEmail)
=09ld.modify(MY_NAME, mod)
=09print "Entry modified"
    except LDAP.Exception:
=09print "Error!"
    if ld.isConnected():
=09ld.disconnect()

Feel free to convert some more to see if you like the feel of it, or
if it reminds you of a way that its done in another python builtin/library.
