          @fanuelsen thanks! Updated and confirmed I can now customize it.

          Trying to SAML auth now gives me a blank page with "Internal Server Error" on it instead, with the displayed URL being the (correct) callback one. Refreshing the page shows a quick Microsoft auth URL then the error.

          Not sure how to proceed here, would help if we could confirm what "Entry point" "Issuer" should be mapped to regarding Azure AD so I could at least rule out the config on XO being the issue. I tried checking Audit and Logs but there wasn't much info on why the auth failed.

              @olivierlambert sorry for the delay there! Relevant portion of the logs (extracted via journalctl -u xo-server.service)

              I looked up "Error: error:0909006C:PEM routines:get_name:no start line" in relation to passport-saml and read through a ton of discussions but couldn't find a conclusive solution. I am copying the contents of the Base64 .cer file in their entirety and triple checked they are correct. Tried converting from UTF-8 to ANSI and ASCII as well as replacing "CERTIFICATE" with "PRIVATE KEY".

              One thing to note: When copying the cert text back from the XO field, the -----BEGIN CERTIFICATE----- and -----END CERTIFICATE----- are not in their own lines. I saw this mentioned in a couple discussions such as here. I did try manually replacing the spaces between the hyphens and the string with /n but it wasn't parsed correctly when entered via the web UI.

                  For what it's worth, most Web UIs I see that take in certs use a text box/area rather than a text field which (directly or indirectly, not sure) preserves the line breaks in the cert. Everywhere I'm seeing, a text field doesn't seem to preserve the needed line breaks when its value is stored in a string.

                  Not sure which file(s) I'd need to edit to test a fix for this as I'm not the strongest with web development, but would be willing to try and report back.

                    Okay thanks for the feedback 🙂 Let's see if we can fix it with a text box/area instead of a simple text field!

                        @julien-f confirmed fixed, thank you! Copy/pasted the Azure AD enterprise app's base64 cert in again and saved to get it working. After updating XO of course.
