Confirmed - it appears to be linked into libgssapi_krb5.so and libkrb5.so,
which in Debian is provided by libgssapi-krb5-2 and libkrb5-3, which are
both direct dependency of the openssh-server package.

The link chain goes like so sshd <- libkrb5.so <- libkeyutils.so

It's in RHEL as far back at least 5.4 (while it exists in 4.6 it's not
linked into ssh), keyutils-libs is a dependency of krb5-libs - so it's
still an indirect dependency of the openssh-server package.
