[flatpak version] cannot connect to EWS with FlatPak build
My last system upgrade broke Evolution. I cannot connect anymore to the Exchange / EWS server. No error message is given.
After, some debugging, the reason is that
- The Ubuntu upgrade of OpenSSL to v3 drops support for MD4 (see below), moved to legacy providers
- The Exchange server expects NTLM authentication, which is based on MD4
My current workaround on Ubuntu 22.04.1 LTS is to tweak /etc/ssl/openssl.cnf
(per https://gist.github.com/rdh27785/97210d439a280063bd768006450c435d, found from here) and use the Ubuntu build.
It'd be great to use the more recent Flatpak build, but I suspect that the Flatpak containerization uses another OpenSSL config.
How to use FlatPak Evolution with EWS/NTLM?
Thanks!
