I have made he script python 2.4 compatible, but before i send a patch i 
have three questions:
1. The script throws an error on the following line of code in 2.4 (2.6 
is fine)
	zeros = b'\x00' * 16
is it safe to remove the string literal, i.e.
	zeros = '\x00' * 16

the results seem to be the same but want to check

2. The getpass module in 2.4 does not play well with redirected output
: when the output is redirected to the file and getpass("Enter LDAP 
Password:") invoked, the prompt string is redirected too. This has two 
negative side effects: users are left wondering what is going on as the 
script seems to be hanging, Enter LDAP Password: becomes part of the 
ldif. This works fine in 2.6

3. the script seems to allow import of only sambaGroupType's of 2 and 4, 
i.e.

  if sgt == SID_NAME_DOM_GRP:
                         gt = GTYPE_SECURITY_GLOBAL_GROUP
                 elif sgt == SID_NAME_ALIAS:
                         #gt = GTYPE_SECURITY_BUILTIN_LOCAL_GROUP
                         gt = GTYPE_SECURITY_DOMAIN_LOCAL_GROUP
                 else:
                         assert False, "sgt[%r]" % (sgt)

I have found an old post 
(http://lists.samba.org/archive/samba-technical/2009-March/063905.html) 
where Volker mentions that s3 supports 2, 4 and 5. Mark is running the 
script and seems to have type 5 in his ldap which stops the script 
execution. Can type 5 be mapped to anything in s4 or is it just 
incompatible?

Thx
