Re: CMIS Java Class connection to Microsoft SharePoint 2013 - Unauthorized

Mon, 11 May 2015 08:58:19 -0700 

Hi Matheus,
We connect to SharePoint repositories all the time via CMIS. And the CMIS Workbench uses exactly the same libary that you are using in your program. If the CMIS Workbench can connect, your program can connect. 


Check the URL, the user and the password again. These are the only 
variables.



You can also catch the CmisUnauthorizedException and call the 
getErrorContent() method. It returns the error message sent by the 
server. It might or might not be something helpful.

Florian,

   Again, thank you for the answer, but unfortunately that didn't
solved the problem.
   Bellow the parameters that I used:

                         //Authentication and binding parameters
                         parameter.put(SessionParameter.USER, user);
                         parameter.put(SessionParameter.PASSWORD, password);
                         parameter.put(SessionParameter.ATOMPUB_URL, host);

			 parameter.put(SessionParameter.BINDING_TYPE, 
BindingType.ATOMPUB.value());


                         //Parameters as in OpenCMIS WorkBench
                         parameter.put(SessionParameter.AUTH_SOAP_USERNAMETOKEN, 
"true");
                         parameter.put(SessionParameter.AUTH_HTTP_BASIC, 
"true");
                         parameter.put(SessionParameter.COMPRESSION, "true");
                         parameter.put(SessionParameter.CLIENT_COMPRESSION, 
"false");
                         parameter.put(SessionParameter.COOKIES, "true");
                        
                         //Workaround parameters
                         parameter.put(SessionParameter.OMIT_CHANGE_TOKENS, 
"true");
                         parameter.put(SessionParameter.ADD_NAME_ON_CHECK_IN, 
"true");

   However, the results are the same:


org.apache.chemistry.opencmis.commons.exceptions.CmisUnauthorizedException:
Unauthorized

    Again, I'm trying to connect to a SharePoint 2013 server (that I
sucessfully connect using OpenCMIS Workbench). All the parameters the
Workbench show me in the expert dialog I've already copied into my
code... Also, there is no proxy configuration.


     Anyone ever tried this kind of connection? Any more workaround I 
could try?


Thanks everyone in advance,

Hi Matheus,

If you can connect with the CMIS Workbench, try the following.

* Connect with the CMIS Workbench.
* Return to the Login dialog and select the Expert tab. Here you should
find the session parameters that were used for this connection.
* Take these session parameters and use them in your Java program.
* If that works, play with the parameters. You probably don't need all
of them for a successful connection.

* If that doesn't work, check if you need additional proxy settings. 
The
CMIS Workbench tries to figure them automatically, but your program 
doesn't.



When everything works fine, also add the following session parameters:

org.apache.chemistry.opencmis.workaround.omitChangeTokens=true
org.apache.chemistry.opencmis.workaround.addNameOnCheckIn=true

They enable workarounds for bugs in the SharePoint CMIS connector.

Hello guys.



Again I send you a message to get some help developing with Apache 
Chemistry.




So, I got this project where I try to connect to a SharePoint 2013 
server using CMIS and to get/"upload" files there.




After the help of Sascha Homeier here on this list, I solved some 
problems and my project now works with the public Alfresco CMIS 
services and a instance of Alfresco I have on my environment. However, 
when I try to use it on SharePoint 2013, I got some problems.



So, my code for connection is:



Session session = CMISServicesImpl.connect(strHost, strUser, 
strPassword);


Folder root = session.getRootFolder();
         ItemIterable<CmisObject> children = root.getChildren();

         System.out.println("Found the following objects in the root 
folder:-");

         ArrayList documentsArray = new ArrayList();
         for (CmisObject o : children) {
         documentsArray.add(o);

             System.out.println(o.getName() + " which is of type " + 
o.getType().getDisplayName());

         }


Basically, the code we all can get on the getting started examples on 
the Chemistry webpage.
When trying to connect to a SharePoint 2013 that have the CMIS 
enabled, as well as basic authentication (I can, for example, connect 
to this repository via CMISSync - a CMIS open source client - or 
Apache Chemistry CMIS Workbench without problems, so the issue are not 
the credentials or the url), I get the following exception:



org.apache.chemistry.opencmis.commons.exceptions.CmisUnauthorizedException: 
Unauthorized



I think that this is something in the communication of my application 
with the SharePoint server... This is a common problem for people that 
try to connect to SharePoint using CMIS on webpages, but there are not 
answers on theses pages...



Another important information: I do this connection using https and 
the server does have a valid certificate.



Also, if I try the same connection inserting a proposital error on the 
url (like a letter where it should be not), the error changes, what 
tells me that if I get this "Unauthorized" error, my application are 
communicating with the SharePoint and the credentials/url data are 
correct.



Anyone here know how can I solve this, or at least understand this 
problem better? Any tip or hint?


Thanks all you guys again,
