Article ID: 186223
A user with a group security community configured and a additional user security community cannot see containers configured with the user security community string.
If the user is part of a group that has a group security community, the security community must be added at the group level.
Release : 10.3
Component : Spectrum Core / SpectroSERVER
The way to do this is to create new group and add the security community to that group and the user will be able to see the container.
