here's the traceback::

the "error" is that this call on ldapobject.py line 557 "e =3D=20
ldap.cidict.cidict(r[0][1])" all of a sudden lowercases the key=20
"subschemaSubentry" from the original search result. so when the code=20
tries to determine the value of that key, and asks for the *camelcased*=20=

version, it will get None back: "e.get('subschemaSubentry',[None])[0]"=20=

because "e" only has a key "subschemasubentry". if "e" contains the=20
original camelcased key then the script continues successfully.
