Troubleshoot Data Archive connection problems

Windows Authentication only uses identity mappings and does not utilize trusts defined with windows credentials for authentication or any other trusts that may be configured. When connecting to Data Archive, error messages might appear if there is no PI mapping configured and one of the following conditions exists:

• You are using a PI username and password to login to Data Archive.

• You are using the default user with a blank password to login to Data Archive.

These errors occur because PI AF 2012 and later has more stringent security settings than earlier versions of PI AF. Clients that connect to Data Archive through PI AF 2012 and later are subject to the following behaviors:

• The default behavior for connections is to not prompt the user for an explicit login unless the Allow login prompt setting is configured. This setting controls what happens when Data Archive authentication fails. If the Allow login prompt setting is enabled, a window opens prompting the user for a username and password. If the setting is off, an error message is displayed. The setting is specific to each client computer. For more information, see Configure clients to allow explicit login prompts.

• Default user connections are no longer supported.

To resolve error conditions, configure PI mappings for users connecting to Data Archive. For more information, see the PI System Management Tools topic Identities, Users, and Groups.
