How to restrict participant on connecting to Domain

Hi, I am new to Canton, and I want to how we can restrict the certain participant on connecting to domain
I have below as the domain.conf and participant1.conf
canton {
domains {
mydomain {
admin-api {
address = “0.0.0.0”
port = 5021
}
public-api {
address = “0.0.0.0”
port = 5022
}
storage = {
type = memory
}
}
}
}

canton {
participants {
participant1 {
admin-api.port = 5011
admin-api.address = “0.0.0.0”
ledger-api {
address = “0.0.0.0”
port = 5012
}
storage = {
type = memory
}
}
}
}

I have 2 more participants.conf file but I want to deny access of participant 3 on connecting to domain when they tries to connect

Hi, @Bhas!

Does the Permissioned Synchronization Domains section answer your question?

…sync domains can also be permissioned , where the operator of the sync domain topology managers needs to explicitly add the participant to the allow-list before the participant can register with a sync domain.

Hi @WallaceKelly
I have added this piece of code in domain.conf but it is giving below error

canton {
  domains {
    mydomain {
      admin-api {
        address = "0.0.0.0"
        port = 5021
      }
      public-api {
        address = "0.0.0.0"
        port = 5022
      }
      storage = {
        type = postgres
        config {
          dataSourceClass = "org.postgresql.ds.PGSimpleDataSource"
          properties = {
            user = "canton"
            password = "canton"
            databaseName = "domain"
            serverName = "postgres"
            portNumber = 5432
          }
        }
      }
    }
  }
  domain-managers.domainManager1.topology.open = false
}

ERROR c.d.c.CantonCommunityApp$ - GENERIC_CONFIG_ERROR(8,0): Cannot convert configuration to a config of class com.digitalasset.canton.config.CantonCommunityConfig. Failures are:

could you please provide me the template of conf file with all allowed keys

@bhas, Can you check the version of Canton you are seeing this error on?

For example, the Permissioned Synchronization Domains feature is only included in the Enterprise edition:

Important
Daml Enterprise license required

Oh, Okay got it I was referring to the version 2.7.9, thanks for confirmation.
