Description Alexey Tikhonov 2025-12-19 15:47:28 UTC
Some of automated SSSD tests started to fail very recently.

Symptoms are as follows:
 - test executes:
```
ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no -o PreferredAuthentications=password -o NumberOfPasswordPrompts=1 -l TESTUSER localhost
```
 - enters password
 - and gets in response:
```
TESTUSER@localhost: Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password,keyboard-interactive).
```

In systemd journal it looks like:
```
sshd-session[665010]: pam_sss(sshd:auth): authentication success; logname= uid=0 euid=0 tty=ssh ruser= rhost=::1 user=TESTUSER
sshd-session[665010]: Failed password for TESTUSER from ::1 port 59358 ssh2
```

SSSD own logs look sane - auth succeeds.

Timing hints this might be related with recent rebase:
https://src.fedoraproject.org/rpms/openssh/c/be36f8dbd60f4d2e7e1e8b21c615a615f1182f84?branch=rawhide

```
# rpm -q openssh
openssh-10.2p1-1.fc44.x86_64
```

Reproducible: Always
