not relevant
- Reverse proxy and version _(e.g. nginx 1.27.2)
not relevant
- PHP version (e.g, 8.3):
not relevant
- Is this the first time you’ve seen this error? (Yes / No):
Yes
- When did this problem seem to first start?
After enabling SAML SSO, user claims normal login works, but the message is not clear
- Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)
docker container
- Are you using CloudfIare, mod_security, or similar? (Yes / No)
not relevant
Summary of the issue you are facing:
I was tasked to enable SSO using Authentik so I chose SAML for SSO setup, after enabling SSO one user claimed that the private key is invalid there for need password. User claims normal login works but i am not sure if that is the case. I have both server side and default encryption enabled. How can I resolve this? Is this a bug?
Steps to replicate it (hint: details matter!):
- Enable SSO, make sure the normal password and SSO password is different
- Use SAML, OIDC can be also tested

Tips for increasing the likelihood of a response
- Use the
preformatted textformatting option in the editor for all log entries and configuration output. - If screenshots are useful, feel free to include them.
- If possible, also include key error output in text form so it can be searched for.
- Try to edit log output only minimally (if at all) so that it can be ran through analyzers / formatters by those trying to help you.
