AADSTS50013 provisioning sign-in failed "assertion is expired, token lifetime exceeded the maximum allowed" SAML error

TL;DR

Fix the SAML assertion lifetime and clock skew: check the identity provider's assertion validity window against the app's allowed lifetime and synchronise clocks, because AADSTS50013 means the assertion had already expired when Entra received it. Prove it on one failing hire before rolling it to the rest of hires in the same sync or flow, because this fault repeats identically wherever the same condition holds and a fleet-wide or batch-wide first attempt multiplies the damage when the diagnosis is wrong.

AADSTS50013 provisioning sign-in failed "assertion is expired, token lifetime exceeded the maximum allowed" SAML error

Use this when

• You see this exact error or symptom: AADSTS50013 provisioning sign-in failed "assertion is expired, token lifetime exceeded the maximum allowed" SAML error.
• The failure is in the provisioning path named in the title (HR source, identity provider, and target app), and it repeats on the same action rather than happening once and clearing.
• Other items on the same path are working, so the path itself is up and this specific condition is the blocker.

Not for this skill when

• A different error code, message, or tool is involved. Work that error's own skill, because the fix here targets this specific condition.
• The whole service or platform is down. Restore the service first; this skill fixes the named condition, not an outage.
• You cannot identify one affected item to test on. Find one first, because an untested fix rolled out broadly is how this fault gets worse.

Steps

1. Confirm the fault on one failing hire first and capture the evidence before changing anything: check the provisioning log entry for the one failing user in the identity provider (Okta system log, Entra provisioning logs, or the target app's SCIM log), and record the exact error text, the record or host involved, and the time it happened. Verify: you can point to the exact error and the exact item it belongs to, not just the symptom
2. Fix the SAML assertion lifetime and clock skew: check the identity provider's assertion validity window against the app's allowed lifetime and synchronise clocks, because AADSTS50013 means the assertion had already expired when Entra received it. Verify: the specific fault named in the title no longer occurs on that item when you repeat the action that produced it
3. Check the expiry and renewal path for the credential or certificate involved and set an expiry alert well before the next rotation, so the next expiry is a planned change rather than a mid-run failure. Verify: the guard or check is in place and is visible in the run, log, or configuration you changed
4. Retest end to end: rerun provisioning for that single user (on-demand provisioning or a sync cycle) and confirm the target account exists with the right attributes and status. Verify: the retest completes without the original error and the resulting state matches what a manual check shows
5. Roll the fix out to the rest of hires in the same sync or flow in the same way, watching the first few for the same error, and note the root cause and the change in the run or incident record. Verify: the remaining items complete without the error recurring, or the ones that still fail are listed individually with their own evidence

Why it happens

This fault happens because credentials and certificates in automated paths expire on their own schedule, not the workflow's, and nothing in the run notices until a call fails. In this case the condition is the one named in the title, in the provisioning path named in the title (HR source, identity provider, and target app): the receiving or acting side reports the failure faithfully, but the underlying state (a record, a setting, a credential, a file, or a mapping) does not match what that action assumes. Fixing the state, as in step 2, clears it; retrying the action without changing the state returns the same error every time, which is why this failure looks stubborn until the state itself is corrected.
