Before anything else you need to add CMIS in your static include in your root template.
This extension provides two record's type :
Cmis Server : adding server with CMIS connector
Cmis Connection : optional, link frontend users and/or groups to a specific authentication in one or more server.
The pages that have these records don't have any importance.
2. Url of endpoint : the url of your CMIS endpoint (sample : http://localhost:8080/alfresco/service/cmis)
3. If you use https check this box
4. REST or SOAP access to your CMIS repository. For the moment let REST!!!
5. The type of server. Normally should be all the time “Generic”.
6 & 7. The login and password that are needed to be authentificated inside the CMIS repository.
