I proposed a merge request on salsa for this issue. https://salsa.debian.org/debian/cyrus-sasl2/merge_requests/2
as a git-format-patch(1) patch: https://salsa.debian.org/debian/cyrus-sasl2/merge_requests/2.patchSee the original message on the bug for how to test the issue. With the package in current unstable/testing, slapd crashes when initializing the smbk5pwd overlay. With this patch, slapd no longer crashes and the module is usable.
