Ann, a technician, is using a saved workflow to deploy virtual servers. The script worked yesterday but is now returning an authentication error. Ann confirms that she can manually log in with her…

Certificate misconfiguration would typically manifest as a specific certificate error, not a generic authentication error, and would likely impact manual login if the same certificates were involved.

If Ann's account was expired, she would not be able to log in manually; if the script uses a different account, 'federation issues' is a broader category often affecting automated identity processes.

Federation issues occur when there are problems with identity providers, trust relationships, or token validation, which can specifically impact automated workflows or service accounts even if a direct user login functions correctly.

Encryption issues usually relate to data confidentiality or secure communication channel establishment, not directly to the authentication process itself.
