Due to that hint with SciLinux I have fetched http://ftp.scientificlinux.org/linux/scientific/7.8/SRPMS/vendor/openssh-7.4p1-21.el7.src.rpm
I can't see it but that is https://bugzilla.redhat.com/show_bug.cgi?id=991186 I can see follow on issues referring to it https://bugzilla.redhat.com/show_bug.cgi?id=1161073 thou. # use default_ccache_name from /etc/krb5.conf (#991186) Patch902: openssh-6.3p1-krb5-use-default_ccache_name.patch The patch is not/no-more in https://git.centos.org/rpms/openssh/blob/c8/f/SOURCES But in https://git.centos.org/rpms/openssh/blob/c7/f/SOURCES/openssh-6.3p1-krb5-use-default_ccache_name.patch That is suspicious, there must be a reason it is gone right? Maybe it was hard to maintain or somewhat bad and they only could drop it on the major version change. In the v8 spec I find: # Improve ccache handling in openssh (#991186, #1199363, #1566494) # https://bugzilla.mindrot.org/show_bug.cgi?id=2775 Patch804: openssh-7.7p1-gssapi-new-unique.patch # Respect k5login_directory option in krk5.conf (#1328243) Patch805: openssh-7.2p2-k5login_directory.patch FYI navigate from here https://git.centos.org/rpms/openssh/blob/c8/f/SPECS/openssh.spec I'm not sure on this, but maybe carrying more of the RH sauce back to upstream might help. Definitely activity on the new or old upstream bug will be needed. Keep us in the loop here what happens. ** Bug watch added: Red Hat Bugzilla #991186 https://bugzilla.redhat.com/show_bug.cgi?id=991186 ** Bug watch added: Red Hat Bugzilla #1161073 https://bugzilla.redhat.com/show_bug.cgi?id=1161073 ** Bug watch added: OpenSSH Portable Bugzilla #2775 https://bugzilla.mindrot.org/show_bug.cgi?id=2775 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1889548 Title: ssh using gssapi will enforce FILE: credentials cache To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/1889548/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
