  3. The issue of CERN CA CRL expiration of Saturday evening 2013/01/19 had a big impact. 6 GGUS tickets (of which 3 are ALARMs) were opened on this issue and its side-effects. The security and middleware evolution groups in the WLCG operations’ area will discuss the CRL update frequency policy and the clarity of the error messages. On EGI request we shall hold a meeting on alternative ways to authenticate to GGUS and other Grid applications on 2013/02/05 at 14:30 CET in CERN room 28-1-025 with remote tel. connectivity arranged. Details in https://savannah.cern.ch/support/?132872 and (still draft) agenda here. Today we offer a username and passwd login but we require the registration of the user’s DN.
