The recent large Windows 10 patch set breaks mapped drives to AFS. OpenAFS v 1.7.32 fixes this. It is hard to find on www.openafs.org, but we've got local copies at https://caligari.dartmouth.edu/downloads/openafs/Windows%2010/ We have also put local copies of the Kerberos libraries and Network Identity Manager on https://caligari.dartmouth.edu/downloads/openafs/Windows%20Kerberos/ These are also hard to find on the web. They are only needed for authenticating with the K5 service, but we're trying to encourage that and retire the old K4 service. The advantages of K5 are stronger authentication, and the ability to use GSSAPI authentication in all the tools which support it. Primarily this means passwordless SSH/SCP to Linux systems for which we've set this up. Contact Research Computing if you need password setup in the K5 system to start using it. The usernames are all the same, and the access controls on the filesystem have no changes. Only the mechanism for obtaining credentials changes for K5. -- Richard Brittain, Research Computing Group, IT Services, 37 Dewey Field Road, HB6219 Dartmouth College, Hanover NH 03755 [log in to unmask] 603-646-2085
