Hmm, this is puzzeling...

Please note that kerberos support is built in, too.  But this happens
automatically, so there's no explicit configure option.

Looks good to me:

$ grep ENABLE_SK config.h
#define ENABLE_SK /**/
#define ENABLE_SK_INTERNAL /**/

I attached my failed-*.log files again.  Curious: Despite defining
TEST_SSH_UNSAFE_PERMISSIONS=1 in the environment. the failed-sshd.log
file contains WARNING: UNPROTECTED PRIVATE KEY FILE! messages, plus
lines like these:

  Unable to load host key "/home/corinna/tmp/openssh/openssh-8.9p0-1.x86_64/build/regress/agent-key.ecdsa-sha2-nistp521.pub": bad permissions

However, these are pub files, not priv files.  Is it possible that
the test fails because srcdir != builddir?


Thanks,
Corinna
