SASLAUTHD error and Funambol

[uxbod]

We are seeing the following when a BB user connects via Funambol; what could be causing it ?

Jan 13 05:19:08 zimbra01 saslauthd[25649]: zmauth: authenticating against elected url 'https://zimbra01.ssiservices.biz:7071/service/admin/soap/' ...

As you can see the user is authenticated okay so from a functional perspective all is working.
