An internal system error occurred - please contact your system administrator: This typically indicates that something has been misconfigured, or a component is not registered or is missing. It could also mean that a catastrophic error has occurred, such as a memory allocation error or a disk full situation that needs the attention of an administrator. Uninstall and reinstall is recommended.
Invalid Username, Password, or One-Time Password: This typically indicates that either the incorrect credentials were entered or that the user did not perform the initial logon when on the domain. The client computer must be able to reach the SecureAuth IdP appliance and the domain for the initial logon so that the seed values can be cached in the registry and so that the computer can be used offline.
An invalid username was entered - please try again: This indicates that the username could not be parsed due to invalid syntax (e..g,, "\", "\username", "domain\").
