Issue

• We have configured three external networks as shared using RHOS4 and now we cannot set this network as unshared.

• On the admin panel (logged as administrator) and over Networks, unchecking shared attribute from horizon shows following error message:

“Error: Failed to update network <name>"

Below trace is found in logs (/var/log/neutron)
