+## Dealing with certificate issues
+
+### Role mismatches
+
+Ciao cluster certificates implement a role base access control (RBAC) system of
+cluster membership.  If a ciao cluster client attempts access using a
+certificate whose embedded role does not match the SSNTP client connection
+indicated role, the access will be disallowed.  The cluster logs will show
+a message, eg:
+```
+Wrong certificate or missing/mismatched role OID
+```
+If this is observed, insure your client certificates are created with the
+correct roles as indicated above, and your client binaries are run with
+configuration using the correct certificate.
+
+### Certificate signed by unknown authority
+
+Ciao cluster certificates are signed by a common certificate authority
+(CA).  The above documentation example creates a trust anchor CA with
+the ```-anchor```, but you can also use a pre-existing one via the
+```-anchor-cert``` option.
+
+Either way, for ciao components to correctly operate, the CA's
+certificate must be in the system trust store on each host running a
+ciao component.  If it is not, you will see cluster log messages, eg:
+```
+x509: certificate signed by unknown authority
+```
+and the cluster will not form.
+
+Depending on your linux distribution, golang runtime, and local IT
+policies, the correct way to add your cluster's CA certificate to
+your cluster systems' trust stores will vary.  Consult your applicable
+documentation.
