Hello, In our xrootd config, we have the following so as to enable authentication/authorisation via the very specific ALICE auth plugin ofs.authorize ofs.authlib /usr/lib64/libXrdAliceTokenAcc.so acc.audit deny grant Do we also need to specify an authdb file? According to the documentation, we have to (since we have ofs.authorize). We removed the reference to an authdb file because we thought that it is not used by ALICE; the tokens/envelopes contain all the authentication/authorisation they need: based on file, operation, file checksum, storage endpoint etc. Or we don't need ofs.authorize at all? Many thanks, George ######################################################################## Use REPLY-ALL to reply to list To unsubscribe from the XROOTD-L list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=XROOTD-L&A=1
