>>> s =
"CN=pointhairedpeoplethatsux,OU=Groups,OU=Hatepeople,OU=HR,DC=fabrika,DC=com;CN=pointhairedboss,OU=Groups,OU=Hatepeople,OU=HR,DC=fabrika,DC=com"
>>> pieces = sum([p.split(';') for p in s.split(',')], [])
>>> pieces
['CN=pointhairedpeoplethatsux', 'OU=Groups', 'OU=Hatepeople',
'OU=HR', 'DC=fabrika', 'DC=com', 'CN=pointhairedboss',
'OU=Groups', 'OU=Hatepeople', 'OU=HR', 'DC=fabrika', 'DC=com']
>>> pieces = sum([p.split(';') for p in s.split(',')], [])

>>> cns
['pointhairedpeoplethatsux', 'pointhairedboss']
The process basically splits on commas, then splits each of those
pieces on semi-colons, then flattens the list-of-lists into a
single list of all the pieces (the flattening is done by abusing
sum() so there may be better, more elegant ways of doing that).
Once you have the flattened list of pieces, you can then just
check for the ones that start with "CN=" and extract the bits of
them that you need.
