Hello,

As a follow up to the previous email, a direct XRootD transfer, from both the XRootD native and the dCache sources, to a local file system using the read envelope pasted below worked fine (and didn't work as expected if the envelope was omitted).

In addition, TPC from EOS sources to our Ceph cluster also work.

Best,

George

Hi George

Would it not be useful to also include the situations where the code works.  e.g. give an example of it working fine with EOS?

Hello, 

We are struggling to make XRootD TPC from XRootD native and dCache sources
work for ALICE. The destination, i.e our, SE is running Ceph (xrootd@proxy and 
xrootd@ceph)

For some reason, the auth read envelope (pasted below) is not passed to the SE and
we get the following errors
 
In the case of XRootD native source

Run: [ERROR] Server responded with an error: [3005] [ERROR] Server responded with an error: [3010] tpc authorization expired (source)

In the case of dCache source
 
Run: [ERROR] Server responded with an error: [3005] [ERROR] Server responded with an error: [3010] An authorization token is required for this request. (source)

If you can give us any clues of what is going on that would be great!  

Many thanks, 

George
