I want to make a Timer job in 2013 (I am on-prem) that can start up multiple workflows. These workflows need to run in a user context that has contribute access to the whole site collection. I understand that by default the Timer job runs as the user context of the OWSTimer service (farm account) and that account is not allowed to kick off workflows.
Can I specify that a workflow start as a specific user? Also, we are using Claims authentication and Negotiate (Kerberos) is the first provider and NTLM is the second (in IIS this is visible / configured). Thanks!
