When attempting to sign in to our newly installed Portal, the option to 'Create An Account' appears and functions correctly. When the account is created have full access to the site and can list Groups and previously created Users. However, the site does not allow existing users to sign in. The message 'Unauthorized' appears in red.
Below is a screenshot of what is appearing.
This issue is similar to one that was previously posted but there was no resolution given. I appreciate any advice.
