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 of problem:
 - Enable oauth2 support in mutt for RHEL8

Why does the customer need this?
 - Microsoft Office 365 is eliminating basic auth for mail service.
   This breaks workflows using RHEL MUAs.

How would the customer like to achieve this? (List the functional requirements here)
 - Enable oauth2 support in RHEL8 mail client "mutt".

For each functional requirement listed, specify how Red Hat and the customer can test to confirm the requirement is successfully implemented.
 - "mutt" can connect to Exchange/Office 365 mail using oauth2

Is there already an existing RFE upstream or in Red Hat Bugzilla?
 - not aware of one

Does the customer have any specific timeline dependencies and which release would they like to target?
 - The ideal timeline is short, unfortunately. There are indications that Microsoft may push the deadline by a few months, but no commitment yet.

Is the sales team involved in this request and do they have any additional input?
 - No

List any affected packages or components.
 - mutt

Would the customer be able to assist in testing this functionality if implemented?
 - Yes
