We use SSO in our environment. When our users sign into the domain, they should be able to access our Intranet site without the need to authenticate again. Some (not all) of our users are having an issue where they launch Chrome or IE, they are getting prompted to enter their credentials (see screenshot). They can access our Intranet after entering their credentials. They place a check mark for "Remember my credentials" checkbox as well. After closing out of their browser and re-launching, the same issue is happening for them. This is causing an inconvenience. This happened after server patching was done. We deploy only Microsoft OS security patches. What can I do to resolve the issue for these users? This is only happening to a handful of users, and not everyone. I already tried having them clear out their browser cache and even resetting IE to default but to no avail.
Is the issue effecting the same users? if so compare the OU they;re in to the ones SSO currently works for. Another thing to try would be to get an effected user to logon to a machine which a working person uses. Do you use thinclients in your environment?
