Hi Gerri, i have this problem client side ( my service is acting as client using the xrootd client), and after the message i got a failure cause GSI is not avaialble as auth method. ( i don't have the exact error message now as i have disabled CRLs verification and in any case to reproduce it i have to wait that the CRL expires). The version is 4.8.3-1 If the error message after that warning is important i will reproduce it and give you also the full GSI debug log cheers Andrea -- You are receiving this because you are subscribed to this thread.
