Description Ravindra Patil 2023-03-28 15:14:48 UTC

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.
