         [-test test only. default: 0]
         -values JSON Object to comprise all config properties to save

REST

Set the maximum number of concurrent web server sessions permissible for a Data Fabric user:

IMPORTANT

If you wish to restrict the maximum number of concurrent user sessions permissible for a Data Fabric user, DO NOT configure spring security concurrency control in session-management. For example, DO NOT use code similar to the following:
```
<session-management>
     <concurrency-control max-sessions="2" />
</session-management>
```
If you change the value for the apiserver.max.concurrent.user.sessions field when the apiserver service is running on your cluster nodes, you must restart the apiserver service on all relevant cluster nodes after changing the value for the apiserver.max.concurrent.user.sessions field.
