Closed User Group (CUG) not working as expected and allowing all users to login
I am testing out Closed User Group (CUG). I followed basic steps for adding CUG for a page (https://experienceleague.adobe.com/docs/experience-manager-64/administering/security/cug.html#security). After following the steps, it adds restrictions to the page and requires login to the page as expected. However, it allows every valid users to login in the page.
To elaborate, if I have group G1 having user U1 part of group and add G1 under Closed User Group from page properties, it should only allow U1 to login to the restricted page. However, it allows other users (U2, U3 for example) as well to access CUG restricted page which is not an expected scenario. To summarize, it allows all valid users to login to the CUG restricted page. To add, I am testing from publisher side, so no dispatcher changes would come into affect here.
