To be more precise, the protocol selection feature *does* work but not via the envar object. You would need to set the process envar XrdSecPROTOCOL; which the XRootD client actually does do and it works as expected. This obviously doesn't work for multi-user applications. So, I assume that is the complaint. Anyway, it will be fixed shortly. --- Reply to this email directly or view it on GitHub: https://github.com/xrootd/xrootd/issues/133#issuecomment-51538224 ######################################################################## Use REPLY-ALL to reply to list To unsubscribe from the XROOTD-DEV list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=XROOTD-DEV&A=1
