Sadly I'd like to get it working on windows. Runas' password can not be set from the command line, so its out of the question. I tried using similar utilities but with no luck (had strange problems with environment variables) and thought that a native condor solution would be the cleanest solution if there is any.You could submit from Linux: sudo -u <username> dag_submit ... But target Windows. From Windows you could use runas and maybe the credentials can be cached for runas (I haven't used it in a while and don't have a Windows machine here right now to check credential caching against). But it requires a human to type the password at least once.
