For POC, we have created dynamics 365 trial and enabled Customer Portal. I registered new user using "Register" option. This user doesn't have any "Web roles" assigned but able to see all the cases available in CRM. I checked in the web role and found "Authenticated Users" roles has set "yes" to "Authenticated Users role". I changed that to "No". But still able to see all cases. Not able to find out why the users is able to see all cases. Please help me to understand the reason for this issue.
Thanks.
