I'm creating a python script which needs to authenticate as an administrator to delegate authentication for various accounts. I want to pull the admin username and password from localconfig so I don't need to store any password in my script (like zmmailbox -z). Using "smtp_source" and "zimbra_ldap_password" gives me the correct username and password, but I would prefer to use the correct keys. I don't see anything like "admin_user" and "admin_password" though. Where do zmmailbox and zmsoap pull the admin account login from?
