vault approle login failed: invalid role id error

TL;DR

AppRole login needs the right role id paired with a valid secret id for an existing role. Most failures mix up the two values or target a deleted role; verify each piece separately.

Error

vault approle login failed: invalid role id error

Steps

1. Confirm the role exists and is enabled at the auth mount. Expected: the role is present.
2. Read back the role id from Vault and compare with what the client sends. Expected: exact match or the mismatch found.
3. Check the secret id is valid and not expired; generate a fresh one to test. Expected: a known-good pair.
4. Verify the client sends role id and secret id to the right fields (they get swapped). Expected: correct mapping.
5. Retry login with the verified pair. Expected: a token.

When to use

• AppRole logins failing with invalid role id.
• Setting up machine auth to Vault.

When not to use

• Token auth failures (different mechanism).
• Permission errors after successful login (policy issue).

Tool compatibility

• Vault AppRole auth method.

Variant phrasings

approle authentication failed

Same triage.

invalid secret id

The other half of the pair.

Why it happens

Role ids are long opaque strings that get truncated or swapped with secret ids, and roles get renamed or deleted while clients keep old values.

Edge cases

• Secret ids expire; a once-working pair stops working on schedule.
• Wrapped secret ids need unwrapping before use; the wrapped value is not the secret id.
• Multiple auth mounts mean the role must be looked up under the right mount.
