This was mentioned by a user on the hn-cms-pysTools list, I'm opening the ticket here for tracking:
As a consequence of the fix for
ROOT-6869 wildcard matching of files in a remote directory is broken (if it is anyway supported by the plugin and endpoint); e.g. TDCacheFile and TNetXNGFile do support it, TWebFile did not, TDavixFile does (with a webdav enabled endpoint). An example of the problem is:
Error in <TNetXNGFile::Open>: [ERROR] Server responded with an error:  Unable to open file /eos/opstest/dhsmith/*.root; No such file or directory
although there are .root files in the directory mentioned.
