I'll look at these. Some appear to occur in standard library routines so we can't do much about that. Others appear to be one-time losses which are expected. I'm surprised you had to do something in your code. The security driver is supposed to try all authentication offered by the server. I hope you are not parsing the security token as that is a really bad thing to do. --- Reply to this email directly or view it on GitHub: https://github.com/xrootd/xrootd/issues/14#issuecomment-17894893 ######################################################################## 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
