Make sure these claims are updated correctly.įor more information, see the following articles for proper client assertion generation: When the Client Assertion is generated, the Public Key to be used is identified in the "kid" or "x5t" claim. Scenario #2: Wrong Public Key provided in Client Assertion request You can either create a brand new key and CSR and send contact support or do a search for all private keys on the system and compare their modulus. If the modulus of the certificate and the modulus of the private key do not match, then you're not using the right private key. Now you should get the modulus as same as certificate modulus above. Openssl rsa -noout -modulus -in myserver.key | openssl md5 Run the following command to view the modulus of the private key. Now you will receive the modulus something like a77c7953ea5283056a0c9ad75b274b96 Openssl x509 -noout -modulus -in server.crt | openssl md5 Run the following command to view the modulus of the certificate. To verify that a private key matches its certificate you need to compare the modulus of the certificate against the modulus of the private key. Scenario #1: Make sure you are using the correct Private Key. This is generally caused when the wrong private key is used to sign the client assertion, or when the wrong Public Key Thumbprint is sent to Azure AD. In addition to what said, here are some other things that could cause the "AADSTS700027: Client assertion contains an invalid signature." error.

After you obtain the thumbprint, please check your code to ensure that it is properly Base64 encoded.Ĭheck the format of your JWT token at jwt.io.ĭrop your private key in to the bottom verify-er which will sign your JWT in the "Encoded" window.
Hi far as I know, this error is usually caused by the fact that you did not encode the thumbprint correctly. data-urlencode 'grant_type=client_credentials' data-urlencode 'client_assertion=xxxx' \ data-urlencode 'client_assertion_type=urn:ietf:params:oauth:client-assertion-type:jwt-bearer' \ header 'Content-Type: application/x-www-form-urlencoded' \ "error_description": "AADSTS700027: Key was found, but use of the key to verify the signature failed.\r\nTrace ID: xxxx\r\nCorrelation ID: xxxx\r\nTimestamp: 17:39:02Z", I'm following the steps mentioned in and to perform client certificate validation but I'm getting below error
