Are you using RC3? With packages updated to the last version?

The "SSL handshake failed: SSL disabled due to library version mismatch" message seems to appear when different versions of libssl are used at compile and runtime.

Do you have a stray libssl or libneon from previous installs?

What does

ls -la /usr/lib/libssl* /usr/lib/libcrypto.so* /usr/lib/libneon*
ldd /usr/sbin/mount.davfs /usr/lib/libneon.so

says? In my system:

As I already told, I'm not able to duplicate the issue, even using the same webdav server.

Are you logged in as root, or using su or sudo? (if that makes a difference...)

Have you configured secrets or whatever davfs2 configuration files? I haven't, used the package right after install.

davfs2 is unconfigured, directly used after install.

my output looks simular to your output, but the size of libneon and libssl is different.

also the numbers of the ldd output at the end of the lines.

you are right.

Somehow I missed that I changed libneon and forget to update the package. As I have a local pkgs feed I didn't notice that.

I have updated the sourceforge package feed now, please try updating neon and report back.

Thanks,

Joao
