No issues from me, I'll let @micolous check too.

I just tried building your branch on my machine with openSSL 3.1.2 and it still fails with the exact same error:

error[E0599]: no associated item named `NO_CHECK_TIME` found for struct `X509VerifyFlags` in the current scope

libopenssl-devel-3.1.2-1.1.noarch

Seems to be working on my tumbleweed machine? Also confirmed it works on my mac with 3.1.2 as well.

Do you potentially have a second openldap/libressl present?

Do you potentially have a second openldap/libressl present?

Yes, I have libressl.

[Firstyear]

Ahh that'll be it. libressl is broken wrt to openssl-rs normally, so it's likely a missing feature/flag/const in libressl.

@micolous I've reverted what fmt changes I can and I don't have enough git-foo to convince the others to calm themselves, I hope that's OK.

[micolous]

Thanks! CI failures on MSRV look like a separate issue not triggered by this change, I've opened #346 about this.
