Final answer:
The issue with missing single sign-on settings could be due to a configuration error, system maintenance, or a bug in the system update. Incorrect user credentials usually lead to login failure rather than missing settings.
Step-by-step explanation:
Issues with Single Sign-On Settings
If expected settings are not found in the 'single sign-on' permission set, there could be several reasons behind this issue. The problem might not necessarily be due to incorrect user credentials, as they usually result in an outright login failure rather than missing settings. It's more likely to be one of the following:
Configuration error: A mistake in the setup process can lead to missing settings. This could be due to misconfigured permission sets or profile settings within the system that govern the availability of certain features.
System maintenance ongoing: If the system is under maintenance, some settings or features might be temporarily unavailable. Users are typically notified about maintenance windows beforehand.
Bug in the system update: Occasionally, updates can introduce unexpected issues that might cause certain settings to disappear or become inaccessible until the bug is fixed.
Investigating these areas can help in determining the correct reason for the missing single sign-on settings.
