Thread: Evolution/EWS not connecting to MS Exchange Server

    Default Re: Evolution/EWS not connecting to MS Exchange Server

    Stuck in the same boat as the OP. Exchange connection is constantly asking for authentication. Glad it wasn't just me. Definitely something that was updated in early April. Was hoping it would be fixed in the next patches.

    A colleage of mine (13.1) and me (42.1) are bitten by the same issue.

    IIRC it was the reboot after updates on Friday 2016-04-15 when the issues started.

    Just a wild guess: evolution uses libnss and there was an update to the ca-certificates-mozilla to 2.7 (but that was installed on 2014-0-18).

    I have no problems putting the ews URL https://your.server/Ews/Exchange.asmx into a browser and authenticating with the AD credentials...

    I submitted a bug 976369. Now someone has found that the cause was the last update of samba-winbind 4.2.4-15.1. They recommended a downgrade to 4.2.4-12.1. I did that and it worked!

    Ah, looks like we got a bugzilla entry https://bugzilla.opensuse.org/show_bug.cgi?id=976110.

    Looks like samba related. (Which was also among the updates installed on 2016-04-15). The linked redhat bugtracker carries very detailed information about it and it appears to have already been fixed over there...

    Ouch, you have been faster. Trying to downgrade as well.

    Downgrad to 4.2.4-12.1 (Leap) did the trick for me as well.

    Caution though: PacakgeKit instantly came up with security updates regarding samba and it installs the -15.1 again.

    Good thing: Verified downgrading works - twice

    As @malcolmlewis said, please help test the packages. I just did and it apparently seems to work. I'd be happier if more then one tested these. Please leave feedback in the bugzilla.
