Jobs submitted from a Windows machine require a stashed password in order for HTCondor to perform certain operations on the user's behalf. RThe command which stashes a password for a user is condor_store_cred. See the manual page for usage details.

The error message that HTCondor gives if a user has not stashed a password is of the form: 

ERROR: No credential stored for username@machinename

        Correct this by running:
            condor_store_cred add
