Lukasz, I am not sure to understand: the old client IS retrying all the protocols offered by the server: it just loops over the list send over by the server, and, in case of failure, destroys the old credential buffer before creating a new one. Why do you say is not? Or are you referring to something different? --- Reply to this email directly or view it on GitHub: https://github.com/xrootd/xrootd/issues/14#issuecomment-17710563 ######################################################################## 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
