CMIS External Authentication

[baaka]

Hello there,

I use external authentication(CAS with LDAP) for Alfresco, now I want to connect Alfresco repository via OpenCMIS.
How can I achieve this? Any suggestions?

p.s. I've tried to connect alfresco via atompub url, passed username/password to parameter, result: CmisUnauthorizedException: Unauthorized

alfresco support authenticating with  ticket using OpenCMIS .Ticket can be specified in password, if any of the following are true:
a) username is not specified (i.e. null, or length of zero)
b) username is equal to "ROLE_TICKET" (case insensitive)
So after a user logged in you can  get the ticket,and use the ticket in OpenCMIS

What if the user isn't authenticating via Alfresco initially, and you are going to divine their User ID from a third party system, and then use External Auth? Can you do that with Apache Chemistry CMIS and Afresco CMIS?
