Tim Golden wrote a useful wrapper for accessing active directory. It is was written for Python 2 but 2to3.py is able to fully translate it. Once downloaded (and updated to 3 if applicable) run python setup.py install to compile and copy the library ready to be used in your programs.
For example to display the user logon name (ID) for all accounts with a name beginning with quackajack (notice the asterisk to do the wildcard search)
import active_directory adusers = active_directory.search("displayName='quackajack*'", objectCategory='Person', objectClass='User') for adu in adusers: print adu.sAMAccountName
If using sAMAccountName seems confusing don’t worry. I struggle to remember all but the most common ones preferring to look them up when needed by listing all attributes then picking the ones I need. If you want to have a look a full list of user attributes is available here.
Those who have used dsquery before from the command line may be aware of the using -attr * to display all attributes of the object. You can do the same in your python script with the dump function. Hence changing the print line above to print adu.dump() will print out a key,value list of all attributes. Be warned its a long list.
