Xmpp dns setup

As the images shows, it can seen on server cb1 , the shared secret used is same as what is being reflected for cb3. After you check on other servers, it is conclude that the entered secret for cb1 is incorrect. Caution : It is recommend to remove xmpp nodes from the cluster before resetting them.

If XMPP reset is performed on a node while it is still in the cluster and then re-join the node to the existing XMPP cluster, it creates a duplicate entry of that node when checked the status through xmpp cluster status.

Please ensure to bundle the certificates xmppserver1. Enable XMPP cluster. After you add all the Call Bridges secret to the second node.

The command list all the secret generated on the first node After all the Call Bridge secrets are added to this node perform these steps. Enter domain for XMPP server domain tptac9.

Usage of the co-located XMPP server reduces latency. For example in the above screenshots Cb1 secret is Callbridge: cb1 Domain: tptac9. This image shows the nodes, one as a Leader Similarly, check the status on rest of the two nodes.

If these errors are seen, check the configuration for SRV records. Scenario 2. When CMS status page shows authentication failure. Please SSH to the server and run this command: xmpp callbridge list The document describes the xmpp resiliency setup. Scenario 3. In xmpp cluster status duplicate entries of XMPP nodes. Your existing Edge topology will replicate changes from the Central Management store to the Edge Server.

You can edit a topology using an account that is a member of the local users group, but publishing a topology requires an account that is a member of the Domain Admins group and the RTCUniversalServerAdmins group. Building an edge and Director topology in Lync Server Configure ports and protocols at the firewall to support the types of federation that you are deploying. Obtain and install public certificates. The time required to obtain certificates depends on which certification authority CA issues the certificate.

This step is optional at this point in the deployment. If you do not perform this step at this point, you must do it during Edge Server configuration. The Edge Server service cannot be started until certificates are obtained. As appropriate to your organization, as these roles are typically split amongst numerous work groups. Transport the exported topology configuration file to each Edge Server or allow replication to complete. Setting up Lync federation in Lync Server The recommended value is 3 and the maximum number of XMPP nodes is currently 5.

Start by connecting to cms1a and disabling the XMPP service as follows:. The database clustering process requires a certificate file that contains all the certificates from all XMPP servers.

If you recall, you created this file when you created the combined certificate file earlier. You named the file cms1abc. All you have to do is configure the XMPP service to look at this file with the following command:.

You can now check the XMPP cluster state. It will start out as a Follower, but should eventually become Leader with only itself as a peer after a few seconds.

Issue the following command a few times until you see the server become a Leader:. You need all XMPP servers to accept those same credentials so you must configure them on the other servers in the cluster. As mentioned earlier you can connect to cms1a and issue the xmpp callbridge list to retrieve the secret values or use the link below to automatically retrieve the secrets you previously created.

You will use the xmpp callbridge add-secret command to configure these credentials on the other servers. On cms1b, do the following. Now you can add cms1b to the cluster. As before, the the XMPP service must first be stopped as follows:. Repeat the same process on the last node, cms1c to enable XMPP and add it to the cluster. Enter these commands on cms1c use the clipboard icon on the right below to copy the all the commands to clipboard then paste :.

Add the Call Bridge credentials for cb-cms1a, cb-cms1b, and cb-cms1c, so they match the ones originally generated just as you did for cms1b. Now set the cluster trust and turn on clustering, which requires the XMPP service to be off. If the start was successful, then you are ready to join cms1c to the cluster leader, cms1a with the following command:.

Now the cluster status shows all three peers with only one leader. Note that this could be any of the servers and after a reboot or other failure, the leader may change. This configuration is done through Web Admin.

You should see that the XMPP connection is in a connected state. The Authentication service should also now show up as registered as a result of being connected to the XMPP server. Later you will configure LDAP for authentication.
