It's a pretty simple regex:
>>> import re
>>>
s='O:owner_sidG:group_sidD:dacl_flags(string_ace1)(string_ace2)...(string_acen)S:sacl_flags(string_ace1)(string_ace2)...(string_acen)'
>>>
>>> m=re.search(r'O:(.*?)G:(.*?)D:(.*?)S:(.*)', s)
>>> m.group(1,2,3,4)
('owner_sid', 'group_sid',
'dacl_flags(string_ace1)(string_ace2)...(string_acen)',
'sacl_flags(string_ace1)(string_ace2)...(string_acen)')
