My service account scopes are : https://apps-apis.google.com/a/feeds/user/ and DriveScope.DRIVE
I authorized this same scope in "Manage third party OAuth Client access" in domain settings for my service account Id.
I use the java client of the provisioning api.
I build my credentials with the google oauth client with a GoogleCredential.Builder :
credBuilder.setTransport(HTTP_TRANSPORT)
.setJsonFactory(JSON_FACTORY)
.setServiceAccountId(config.serviceAccountId)
.setServiceAccountPrivateKeyFromP12File(new File(config.keyFilePath))
.setServiceAccountScopes(SCOPES);
.setServiceAccountUser("admin.of.my@domain.com")
I try to authorize my request to the provisioning api with
userService = new UserService(config.repositoryId);
userService.setOAuth2Credentials(oAuthCredentials);
where oAuthCredentials are my previously built Service credentials.
With that configuration i can access files and collections from the Google Drive of any user of my domain. But i can't acces the list of users of my domain with those credentials.
If i dont specify the service account user, it doesn't work either
Here is the stack trace i get :
com.google.gdata.util.ServiceForbiddenException: You are not authorized to access this API.

After investigation it seems that getting a 403 error happens if the account that is set in .setServiceAccountUser("admin.of.my@domain.com") is not a "Super Admin" of the domain.
However in the case above "admin.of.my@domain.com" is indeed a Super Admin of the domain. Also the code works well with any other Super Admin of the domain which leads to believe that there is something wrong with the account "admin.of.my@domain.com" in particular.
If this happens to anyone else - a.k.a. an account set as "Super Admin" which does not work to access Admins-only APIs through Service Accounts - make sure you let us know in the comments below and we'll investigate further if this impacts lots of people.
Now provisioning APIs have been deprecated as of 15th of May 2013. They have introduced new set of APIs called Directory APIs which solves your problem.
