How are "all users" authenticate to your CEPH/Xrootd gateway?

    Hi Max,
    
    
    Thanks for this. I was refering basically on the xrootd@proxy service running on a Ceph gateway.
    
    
    Do you mean to change the user/group settings in [log in to unmask]
    
    from "xrootd" to "alicesgm" ?
    
    
    What about the xrootd@ceph service?

    Hi George,
    
    while it is not exactly what you are asking for:
    We simply run all ALICE xrootd services as the respective alicesgm user. That automatically maps all users to this identity for operations on the file system etc.
    
    Cheers,
    Max
