I have the following problem: the krb5 & gsi plugins use either an environment variable or if not set geteuid to define the token/proxy location for authentication. In a multithreaded application it is not possible to have thread-private environment variables or effective uids thread-private, so I cannot use this mechanism unless I created a lock environment and set this variables for each individual XRootD call, which kills parallelism/performance. The simplest way for me would be to pass the two relevant variables with each URL e.g. "root://host//myfile?env:KRB5CCNAME=/tmp/krb5cc_QQWIUQIWUE1239873" --- Reply to this email directly or view it on GitHub: https://github.com/xrootd/xrootd/issues/8 ######################################################################## 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
