Multiple krb5 tickets causes evolution-ews confusion
I have Evolution (3.38.3) configured with ews for my corporate email account. This depends on an active krb5 ticket from my corporate krb5 server. However, in my role as a Fedora contributor, I need to kinit a second krb5 ticket from FEDORAPROJECT.ORG, and having two krb5 tickets at the same time seems to confuse Evolution, to where it mashes the two hostnames together. The easy fix is to re kinit against my corporate krb5 server, and then Evolution can reconnect.
I suspect there is something in the ews code which assumes only one krb5 ticket is in use at any given moment, which is an incorrect assumption.
The next time this happens, I will get a screenshot.
