You could start by splitting

>>> x = b'CN=User1,OU=DEVELOPER,OU=DEFAULT,OU=TURKIYE,OU=GLOBAL,DC=TRADONS,DC=local'
>>> L = [t.split(b'=', 1) for t in x.split(b',')]
>>> L
[[b'CN', b'User1'], [b'OU', b'DEVELOPER'], [b'OU', b'DEFAULT'], [b'OU', b'TURKIYE'], [b'OU', b'GLOBAL'], [b'DC', b'TRADONS'], [b'DC', b'local']]
