Summary

Users who are members of administration groups and don't have Jira application access, won't have permission to projects on Customer Portal.

Steps to Reproduce

1. Add user to a Jira admin group (administrators, site-admins or any other group with admin permissions)
2. Make sure that the user doesn't have a Jira application access (JSM/JSW/JWM)
3. As the user, send an email to JSM, or try logging into the portal

Expected Results

• User will be able to view the project on the portal.
• The user's message will be processed.

Actual Results

• You do not have permission to view this Portal.
• The following error will show up in the processing logs: Sign up not available. 

Notes

• Adding the affected user as a Reporter or Request Participant of a JSM request will result in the error: Cannot add user <user> because they are not a customer on this service project

Workaround

• Remove user with no product access from jira-administration groups.
• Admin to get product license as it wont be supported for admin to have application access without proper licensing
