Description of problem:
I am not able to  ssh-agent / pam_ssh_agent_auth. Reproducible by /CoreOS/openssh/Sanity/pam_ssh_agent_auth . I am suspecting this is related to SHA-1 disablement, because things work fine with LEGACY crypto policy.

Version-Release number of selected component (if applicable):
openssh-8.7p1-8.el9

How reproducible:
always

Steps to Reproduce:
... see the test

Actual results:
:: [ 13:56:08 ] :: [  BEGIN   ] :: Running 'su testuser11049 -c 'eval `ssh-agent`; ssh-add ~/.ssh/my_id_rsa; sudo id; ssh-agent -k''
Agent pid 59937
Identity added: /home/testuser11049/.ssh/my_id_rsa (testuser11049.pnr.lab.eng.rdu2.redhat.com)

We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:

    #1) Respect the privacy of others.
    #2) Think before you type.
    #3) With great power comes great responsibility.

sudo: a terminal is required to read the password; either use the -S option to read from standard input or configure an askpass helper
sudo: a password is required
unset SSH_AUTH_SOCK;
unset SSH_AGENT_PID;
echo Agent pid 59937 killed;
:: [ 13:56:08 ] :: [   PASS   ] :: Command 'su testuser11049 -c 'eval `ssh-agent`; ssh-add ~/.ssh/my_id_rsa; sudo id; ssh-agent -k'' (Expected 0, got 0)
:: [ 13:56:08 ] :: [   FAIL   ] :: File '/var/tmp/rlRun_LOG.LGTLJGZu' should contain 'uid=0(root) gid=0(root)' 

Expected results:
works
