16:35 → 16:45 Tape REST access

16:45 → 17:00 Transfers with tokens

Speakers: Petr Vokac (Czech Technical University in Prague (CZ)), Francesco Giacomini (INFN CNAF)

Alma9 xrd client & sites with Root CA signed by SHA1

• Is it a mistake that XRootD client verify signature of self-signed Root CA?
• Alma9 (lxplus) issue with certificates where IGTF Root CA use self-signed with SHA1
  • only problems with xroot protocol
  • create XRootD issue issue#2150

Rucio + FTS with tokens

• details in the "Rucio Token Support" persentation last week in WLCG DOMA General
• FTS implemented configurable token issuer -> VO mapping (FTS-1987)
  • Rucio can't easily use tokens & X.509 to query FTS for transfers submitted with tokens vs. X.509
    • Now Rucio can get all VO transfers independently on authorization with FTS
  • Require special FTS branch / build
    • deployed on CERN FTS pilot
      
      • most probably it'll be deployed also on ATLAS and CMS instance for DC24
    • to be clarified participation of non-CERN FTS servers

StoRM stat with tokens

• support for "stat" with storage.create and storage.modify STOR-1600

dCache support for fireflyes

• Still issues ... may be dCache 9.2.7
• Too late for DC24 ...

IAM 1.8.3

• to be deployed at CERN before Xmas
• voms-impoter needs to be updated to synchronize AUP date
  • ATLAS IAM instance now temporarily configured with 10 years AUP
  • otherwise users would have to sign AUP in both - legacy VOMS and IAM VOMS
