#### Joining with a Secret Key In addition to an invitation hash, you can join a Tenant to the Tenant Broker using a secret key. As described earlier, a secret key can be used to join an unlimited number of Tenants to the same Tenant Broker. To create a secret key: Log in to the Tenant Broker console. In the RAS Console, navigate to Farm / Settings. Select the Tenant broker tab. Select the Allow RAS Farms to register in Tenant Broker using a secret key. The secret key is generated automatically. To generate a different key, click Generate. Once you have the key, you can use it to join one or more Tenants to the Tenant Broker. Note: Due to its unlimited usage capability, only the Tenant Broker administrator should have access to a shared secret key. Secret keys can be practical when the Tenant Broker administrator manages Tenant Farms, so instead of generating a hash for every Tenant, he/she can use a single secret key to join all of them to the Tenant Broker. To join a Tenant using a secret key: Log in to the Tenant Farm. In the RAS Console, navigate to Farm / Site. Click Tasks > Join Tenant Broker. In the Join Tenant Broker dialog, enter the secret key and then enter a Tenant name of your choosing. The name you enter will be used in the Tenant Broker to name the corresponding Tenant object. Click Join. On successful join, you will see a message welcoming you to the Tenant Broker. If the primary Publishing Agent in your Tenant Farm can't reach the Tenant Broker, you will see a corresponding error message. Make sure that the Tenant Broker computer is reachable from the machine where you have the primary Publishing Agent running. Overriding the Tenant Broker IP address The Tenant Broker IP address is detected automatically when you generate a secret key and is embedded into it. If a Tenant can't reach the Tenant Broker using this address, you have the ability to override it as follows: Log in to the Tenant Broker. In the RAS Console, navigate to Farm / Settings and click the Tenant broker tab. Select the Override Tenant Broker address in tenant invitations and secret keys option. Enter the desired IP address in the field provided.
