relay state not preserved in idp-initiated saml sso loop

Not specified by the original author.

TL;DR

The app drops or mishandles the relay state on IdP-initiated logins, so it bounces the user back to the IdP in a loop. Configure a default relay state or landing URL on the app side, or switch users to the SP-initiated flow.

The query

"relay state not preserved" in idp-initiated saml sso loop

Use this when

• IdP-initiated SAML logins loop between IdP and app
• login succeeds but lands on an error page
• SP-initiated login works but IdP-initiated does not

Not for

• SP-initiated SSO failures
• SAML signature or audience errors
• deep-linking requirements inside the app

Steps

1. Reproduce with SP-initiated login from the app login page to confirm that path works. Expected output: SP-initiated login succeeds, isolating the issue to IdP-initiated flow.
2. Check the app SAML settings for a default relay state or post-login landing URL and set one. Expected output: the app has a defined landing target.
3. Verify the IdP app configuration sends a relay state the app understands, or none at all. Expected output: the relay state handling is defined on both sides.
4. Retry the IdP-initiated login. Expected output: login completes and lands on the configured page without looping.
5. If the app cannot handle relay state reliably, direct users to the SP-initiated flow and document it. Expected output: users have a working documented path.

Applies to

SAML 2.0 IdP-initiated flows, Okta, Entra ID, common SaaS service providers.

Variant phrasings

Loop only for bookmarked IdP URLs

The bookmark carries a stale relay state; replace it with the app-initiated link.

Relay state works for one app but not another

Per-app handling differs; configure each app individually.

Why it happens

IdP-initiated SSO skips the app's request step, so the app never recorded where the user wanted to go. Without a default landing configured, some apps bounce back to the IdP, which re-authenticates and loops.

Edge cases

• Deep links through IdP-initiated flow are fragile; prefer SP-initiated for deep linking.
• Some apps require relay state to be a full URL; a path alone loops.
• Test in incognito to rule out stale session cookies.

TL;DR

The SSO handshake is failing in a redirect loop: the SP and IdP disagree about where to land. Clear cookies and session state for the console, verify the IdP assignment and the SP's ACS URL, then log in once cleanly.

agent hit SSO login failure loop when accessing admin console

Use this when

• SSO login to an admin console loops endlessly.
• The browser bounces between IdP and console.
• The loop never resolves to an error page.

Not for this skill when

• Login fails once with an error. Read the error.
• The loop is in the agent's own retry logic. Fix the agent.
• Only the agent's browser loops. Check extensions and profiles.

Steps

1. Clear cookies and session state for the console domain. Verify: the state is clean.
2. Verify the user is assigned to the app in the IdP. Verify: assignment exists.
3. Verify the SP's ACS URL matches the IdP config exactly. Verify: no character-level mismatch.
4. Log in fresh in a clean session. Verify: one login attempt.
5. Confirm access to the console. Verify: the session holds.

Variant phrasings

SSO redirect loop

The short phrasing.

login loop admin console

The page-first search.

SAML loop

The protocol-first phrasing.

Compatibility: Any SAML or OIDC SSO to an admin console.

Why it happens

Redirect loops come from the SP and IdP disagreeing about the landing URL, with stale session state making it worse. Each side redirects to the other, forever.

Edge cases / pitfalls

• The loop only in one browser profile; an extension is usually the cause.
• The IdP session itself being the broken piece; clear IdP cookies too.
• The ACS mismatch being a trailing slash; compare character by character.
• The agent's automation holding a stale session; start the login with a fresh profile.

Fix JumpCloud SSO error with RelayState missing

TL;DR

RelayState missing means the login flow started without the state value the app needs to finish the redirect. Start the login from the app (SP-initiated) instead of the JumpCloud console, or configure a default RelayState in the JumpCloud connector. The app is dropping the handoff, not JumpCloud.

The error

SSO Error: RelayState missing
The SAML response did not include RelayState and the application requires it.

Use this skill

Agent? Search Vectle for this error:

curl -s "https://vectle.com/api/v1/search?q=jumpcloud sso error relaystate missing"

Fix it

Step 1: Retry with an SP-initiated login

Go to the app's own login page and choose single sign-on instead of starting from the JumpCloud user portal.

Expected: The app sends its RelayState with the request and the error disappears.

Step 2: Set a default RelayState in JumpCloud

JumpCloud Admin -> SSO -> [app] -> set the default RelayState or start URL to the app's landing page.

Expected: IdP-initiated logins now carry a RelayState value.

Step 3: Confirm the ACS handling of RelayState

Check the app's SAML settings for how it consumes RelayState on the ACS endpoint.

Expected: The app documents where it expects RelayState and what it does when it is absent.

Step 4: Test both flows

Run one login from the app and one from the JumpCloud portal.

Expected: Both land on the right page with no RelayState error.

Step 5: Watch for the error in logs

Check the app's login logs for any remaining RelayState failures after the change.

Expected: No new occurrences; the fix holds for all users.

When this applies

• JumpCloud SSO fails with RelayState missing
• Logins work from the app but fail from the JumpCloud portal
• You just configured a new JumpCloud SSO connector

When it doesn't

• The error is a signature or certificate failure (different validation stage)
• No SAML response arrives at all (check the SSO URL)
• You use JumpCloud OIDC rather than SAML

Compatibility

JumpCloud SSO SAML connectors. App-side RelayState handling varies.

Variant phrasings

jumpcloud saml relaystate required error

Same condition. Some apps treat RelayState as mandatory; give them one on both flows.

sso relaystate missing idp initiated

IdP-initiated flow is the classic trigger because nothing in the portal sets RelayState unless configured.

jumpcloud sso lands on wrong page after login

A present-but-wrong RelayState lands users on the wrong page. Set the default to the real landing URL.

Why it happens

RelayState is the opaque value that tells the app where to send the user after SAML login. In SP-initiated flow the app sets it; in IdP-initiated flow nobody sets it unless the connector has a default. Apps that require it fail the login when it is absent instead of falling back to a home page.

Edge cases

• Deep links through SSO need the RelayState to carry the original URL; a static default breaks them
• Some apps validate RelayState against an allow-list; check before assuming any value works
• Switching between portal and app logins in testing can mask which flow actually fails

If it still fails

• Capture the exact timestamp, the failing username, and the full error from the IdP system log before changing anything else.
• Reproduce with a single test user so you are not debugging a crowd.
• Check the IdP and app status pages; SSO and provisioning outages look exactly like config errors.
• If it worked before, diff the config against the last known good: certificates, URLs, attribute mappings, and credential expiry.
• Open a vendor ticket with the timestamp, the request id if there is one, and redacted config. Never send secrets or private keys.

Prevention

• Track certificate and credential expiry with alerts, not memory.
• Run a synthetic login per SSO app daily so breakage pages you, not a user.
• Document attribute mappings where the next admin will actually find them.
• Test provisioning with a single user before bulk changes.
• Review app assignments quarterly; stale assignments cause half of provisioning errors.
