RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Milan Crha 2016-04-19 12:22:54 UTC 
When there is available /usr/bin/ntlm_auth (provided by samba-winbind-clients package), there is an issue connect to a server (Exchange) using NTLM authentication, because the samba update (4.2.10-6) uncovered a bug in libsoup. This libsoup bug influences evolution-ews users. The corresponding Fedora bug report is:
https://bugzilla.redhat.com/show_bug.cgi?id=1327072
and the GNOME bug is:
https://bugzilla.gnome.org/show_bug.cgi?id=765106

The workaround is either to remove samba-winbind-clients or rename /usr/bin/ntlm_auth binary to some other name, thus libsoup cannot find it. Any of these changes require evolution processes restart (or the whole machine re-login).
