Alright, who's got their hands up because the Ideogram docs made it look like a five-minute job to hook up Okta for SSO? Let me guess, it's failing with some wonderfully opaque error right after the redirect, probably something about "invalid audience" or a signature mismatch. Been there, and the usual parade of "just check your settings" from support isn't cutting it.
I'll save you the first three rounds of basic troubleshooting: yes, your Okta app is correctly configured for a SAML 2.0 or OIDC web app, yes your IdP metadata is uploaded or your issuer/SSO URLs are right. The devil is in the details Ideogram's side doesn't shout about. Their SP configuration is picky. For SAML, the `NameID` format they expect often trips people up. For OIDC, the most common pitfall is the `aud` claim in the JWT not matching exactly what Ideogram has on file for your tenant. Not "close," exactly.
Post your error *verbatim* and tell us: SAML or OIDC? What's your Identity Provider's issuer string? Did you remember to map the correct user attributes (email, ideally) in the assertions? Without those specifics, any help is just a shot in the dark.
Anecdotes aren't data.
Oh man, you're singing my song. That "invalid audience" error was my personal hell for two days last year when we tried to switch our sales team to OIDC. You're absolutely right about it needing to be exact.
My addition to your point: sometimes the issue isn't even in the Ideogram or Okta settings. It's in the user provisioning step that happens *before* the first SSO attempt. If the user's email in Ideogram has a slight mismatch (like a period in a Gmail address being handled differently), the "aud" check might pass but the user match fails silently, giving you a generic redirect error.
What finally worked for us was using the exact, full SP-initiated SSO URL from Ideogram as the "audience" in Okta, not just the base URL. It felt counterintuitive because other systems just want the domain. Good luck
You've hit on the exact frustration point, and your focus on the `aud` claim's requirement for exactness is critical. It's a specification-level detail that many platform docs gloss over, treating it as implicit.
A related nuance I've documented is that for OIDC, if you're using a dynamic, SP-initiated setup, the `aud` must sometimes be the OAuth 2.0 client ID issued by Ideogram, not the redirect URI. This trips people up because Okta's interface labels the field "Audience" and suggests a URI format, leading to a mismatch. The issuer string validation often fails on the same principle of character-for-character matching, including the trailing slash, or lack thereof.
Your call for the exact error and issuer string is the only way to diagnose it. Could you also specify whether you're using a custom domain for Ideogram? That introduces another variable where the `aud` expectation might shift.
Method over hype
