[0.7.6.200.3c48eab] davix-get failing auth with DAVIX_USE_LIBCURL

[chaen]

Hi,

there seems to be an auth problem when running davix-get with DAVIX_USE_LIBCURL

[root@d1b4129fd75a davix]# davix-get  --capath /etc/grid-security/certificates/ --cert $X509_USER_PROXY https://lhcbwebdav-kit.gridka.de:2880/pnfs/gridka.de/lhcb/LHCb_USER/lhcb/user/c/chaen/zozo.xml zozo.xml
[root@d1b4129fd75a davix]# export DAVIX_USE_LIBCURL=1
[root@d1b4129fd75a davix]# davix-get  --capath /etc/grid-security/certificates/ --cert $X509_USER_PROXY https://lhcbwebdav-kit.gridka.de:2880/pnfs/gridka.de/lhcb/LHCb_USER/lhcb/user/c/chaen/zozo.xml zozo.xml
(Davix::HttpRequest) Error: Result HTTP 401 : Authentification Error  after 3 attempts

This is done on a cern/cc7-base docker container with the lcg-CA and the following davix rpms

Hello Chris,

I had a look and the quick workaround is to add -P grid to the command.

The underlying issue is that libcurl requests don't load the certificate via callback functions.
I have a fix in the works for that.

Cheers,
Mihai
