The file that will store the credentials is named as drm-batch-client-credentials.exe – within this file the credentials for that specific Windows account will be stored. Interesting to note, if I login with a different Windows account and try to run the DRM Batch Client, it will not run because the credentials though already stored is for the other Windows account. So I need to login using that Windows account for my DRM Batch Client to to work successfully, otherwise I need to configure the DRM Batch Client credentials for all the possible Windows accounts that are present so that all the accounts can use the DRM Batch Client fine.
While setting up the DRM Batch Client, I would be interactively prompted with a few options whether I want to erase the existing credentials, or update the existing credentials etc. On selecting the the correct option and entering the credentials as requested, I am done configuring the DRM Batch Client successfully. On all future DRM Batch Client tasks, these are the credentials that will be used. This username thus can be found in all the audit logs going forward for all the activities performed by the DRM Batch Client.
