@abh3 Thanks, indeed I got the `grpopt` numbers flipped! Sorry for that. However, I can also reproduce the problem with "12": ``` sec.protocol /usr/lib64 gsi -dlgpxy:1 -exppxy:=creds -ca:1 -crl:3 -gridmap:/dev/null -cert:/etc/grid-security/hostcert.pem -key:/etc/grid-security/hostkey.pem -certdir:/etc/grid-security/certificates -vomsfun:/usr/lib64/libXrdSecgsiVOMS.so -vomsfunparms:certfmt=raw|vos=atlas,ops,dteam,wlcg|grps=/atlas,/ops,/dteam,/wlcg|grpopt=12 ``` (i.e. authentication for any but the first VO fails) vs. ``` sec.protocol /usr/lib64 gsi -dlgpxy:1 -exppxy:=creds -ca:1 -crl:3 -gridmap:/dev/null -cert:/etc/grid-security/hostcert.pem -key:/etc/grid-security/hostkey.pem -certdir:/etc/grid-security/certificates -vomsfun:/usr/lib64/libXrdSecgsiVOMS.so -vomsfunparms:certfmt=raw|grpopt=12|vos=atlas,ops,dteam,wlcg|grps=/atlas,/ops,/dteam,/wlcg ``` which works fine. Interestingly, it also fails if I completely remove `grpopt`. My understanding of the code / documentation was that `12` is the setting which will automatically be used if `grps` is set. I'm using `xrootd` 4.12.1 (with `xrootd-voms` 4.12.1). -- You are receiving this because you are subscribed to this thread.
