Related bug track mentioned here.

It seems this is related to openssl itself no longer supporting "legacy" hashing algorithms (e.g. MD4).

I've made the suggested changes to my /usr/lib/ssl/openssl.cnf file, but unfortunately, it makes no difference. This is almost certainly because I'm missing something obvious, but I've never fiddled with OpenSSL. I'm hoping I don't have to reboot my machine.

See #1051 for an explanation and a possible workaround (manually installing pycryptodome).

Receiving "unsupported hash type MD4" when trying to auto-join the domain controller. Per this issue (cannatag/ldap3#1038) with the ldap Python library, adding pycryptodome==3.18.0 to the requirements.txt fixes the issue.
