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:

lftp not working with re-newed certificates

- The certificates were expired for site. 

- We got new Certificates and replaced the files used by Apache (Web Server). 

- The CA Chain is not changed. Only certificate re-newed

- The certificates work everywhere for same site(e.g. various webbrowsers, curl, openssl connect, gnutls-cli) except for lftp.

-  lftp connection works fine on disabling the ssl verification.


Version-Release number of selected component (if applicable):
lftp-4.8.4-2.el8.x86_64.rpm

How reproducible:

- Renew ceritificates and try connect to site through lftp with SSL enabled 

Steps to Reproduce:
1.  Obtain re-newed certificate
2.  Move them to respective locations as per apache configuration
3.  Try connecting over lftp with SSL enabled

# lftp site-name.example.com 

Actual results:

Connection fails with error "Fatal error: Certificate verification: Not trusted: no issuer was found (C4:3F:D4:BD:3C:BA:B7:8C:45:B1:6B:87:3B:C0:7B:A4:CF:32:99:A2)

Expected results:
Secure connection should be established, as it does for other tools like curl, openssl connect etc.
