MATLAB Web App Server shows "No web apps available. Add valid web apps to the apps folder in the MATLAB Web App Server."

I have enabled Authentication for my MATLAB Web App Server and I can log in and see all the apps. After I enabled Policy-Based Access, I got the following error: "No web apps available.Add valid web apps to the apps folder in the MATLAB Web App Server."

This is because the policy you defined in the webapps_authn.json file limits your access to any of the apps. Please check the rules you defined if you believe you should have access. 

For example, if you are using LDAP Authentication, you can check if you have the right attribute value.

Using below rule as an example, you can check if you are a member of "cn=Sales,ou=sales,ou=groups,dc=myboston,dc=com" or if the spelling of the attribute value "cn=Sales,ou=sales,ou=groups,dc=myboston,dc=com" is correct. 

"id": "rule101",
          "description": "Sales group can run the BloodPressure app.",
          "subject": { "memberOf": ["cn=Sales,ou=sales,ou=groups,dc=myboston,dc=com"] 

You can perfrom a ldapsearch to get your ldap entry value. You might refer the following article for more details.
