Description of problem: Can't perform REX from Satellite 6.8 UI on RHEL 8.2 when FUTURE crypto policy is set. But ssh as foreman-proxy user, from CLI, works just fine. Version-Release number of selected component (if applicable): Satellite 6.8 RHEL 8.2 [ Hopefully 8.3 as well ] Crypto Policy: FUTURE [ FIPS as well ] How reproducible: Always Steps to Reproduce: 1. Ensure Satellite 6.8 is configured as per https://access.redhat.com/solutions/5393241 2. Register a RHEL 8.2 host with Satellite and the RHEL 8.2 host must have the crypto-policy set as FUTURE. 3. Copy the foreman-proxy ssh keys to the RHEL 8 host and test ssh connectivity from command line. 4. Initiate a simple "uptime" command-based REX job from satellite UI for the same host. Actual results: 3 is successful but at 4 i.e. REX from UI, the job will fail with the following error. ~~ Error initializing command: Net::SSH::AuthenticationFailed - Authentication failed for user root.com ~~ Expected results: 3 and 4 both should succeed. Additional info: As soon as we set back the crypto policy to LEGACY or DEFAULT, REX will work just fine.
Verified on Satellite 7.0 snap 4, both ansible and ssh type rex job ran successfully against RHEL8 host with FUTURE crypto policy enabled
