Error code search

InvalidResourcelessScope - The provided value for the input parameter scope isn't valid when requesting an access token.

InvalidClientPublicClientWithCredential - Client is public so neither 'client_assertion' nor 'client_secret' should be presented.

Client assertion failed signature validation. Developer error - the app is attempting to sign in without the necessary or correct authentication parameters.

UnsupportedGrantType - The app returned an unsupported grant type.

Invalid certificate - subject name in certificate isn't authorized. SubjectNames/SubjectAlternativeNames (up to 10) in token certificate are: {certificateSubjects}.

InvalidRedirectUri - The app returned an invalid redirect URI. The redirect address specified by the client does not match any configured addresses or any addresses on the OIDC approve list.

UnsupportedResponseType - The app returned an unsupported response type due to the following reasons: response type 'token' isn't enabled for the app response type 'id_token' requires the 'OpenID' scope -contains an unsupported OAuth parameter value in the encoded wctx

Response_type 'id_token' isn't enabled for the application. The application requested an ID token from the authorization endpoint, but did not have ID token implicit grant enabled. Sign in to the Microsoft Entra admin center as at least a Cloud Application Administrator and then browse to Entra ID > App registrations. Select your application and then select Authentication. Under Implicit grant and hybrid flows, make sure ID tokens' is selected.

UnsupportedResponseMode - The app returned an unsupported value of response_mode when requesting a token.

ExpiredOrRevokedGrant - The refresh token has expired due to inactivity. The token was issued on XXX and was inactive for a certain amount of time.

ExpiredOrRevokedGrantInactiveToken - The refresh token has expired due to inactivity. The token was issued on {issueDate} and was inactive for {time}. Expected part of the token lifecycle - the user went an extended period of time without using the application, so the token was expired when the app attempted to refresh it.

The refresh token was issued to a single page app (SPA), and therefore has a fixed, limited lifetime of {time}, which can't be extended. It is now expired and a new sign in request must be sent by the SPA to the sign in page. The token was issued on {issueDate}.

InvalidScope - The scope requested by the app is invalid.

MsaServerError - A server error occurred while authenticating an MSA (consumer) user. Try again. If it continues to fail, open a support ticket

AuthorizationPending - OAuth 2.0 device flow error. Authorization is pending. The device will retry polling the request.

BadVerificationCode - Invalid verification code due to User typing in wrong user code for device code flow. Authorization isn't approved.

CodeExpired - Verification code expired. Have the user retry the sign-in.

ForbiddenTokenType- Only app-only tokens can be used as Federated Identity Credentials for Microsoft Entra issuer. Use an app-only access token (generated during a client credentials flow) instead of a user-delegated access token (representing a request coming from a user context).

BadTokenDueToSignInFrequency - The refresh token has expired or is invalid due to sign-in frequency checks by Conditional Access. The token was issued on {issueDate} and the maximum allowed lifetime for this request is {time}.

BindingSerializationError - An error occurred during SAML message binding.

UnsupportedBindingError - The app returned an error related to unsupported binding (SAML protocol response can't be sent via bindings other than HTTP POST).

Saml2MessageInvalid - Microsoft Entra doesn’t support the SAML request sent by the app for SSO. To learn more, see the troubleshooting article for error AADSTS75005.

A supported type of SAML response was not found. The supported response types are 'Response' (in XML namespace 'urn:oasis:names:tc:SAML:2.0:protocol') or 'Assertion' (in XML namespace 'urn:oasis:names:tc:SAML:2.0:assertion'). Application error - the developer will handle this error.

The value ‘SAMLId-Guid’ isn't a valid SAML ID - Microsoft Entra ID uses this attribute to populate the InResponseTo attribute of the returned response. ID must not begin with a number, so a common strategy is to prepend a string like "ID" to the string representation of a GUID. For example, id6c1c178c166d486687be4aaf5e482730 is a valid ID.

SAMLRequest or SAMLResponse must be present as query string parameters in HTTP request for SAML Redirect binding. To learn more, see the troubleshooting article for error AADSTS750054.

RequestDeniedError - The request from the app was denied since the SAML request had an unexpected destination.

NoMatchedAuthnContextInOutputClaims - The authentication method by which the user authenticated with the service doesn't match requested authentication method. To learn more, see the troubleshooting article for error AADSTS75011.

Saml2AuthenticationRequestInvalidNameIDPolicy - SAML2 Authentication Request has invalid NameIdPolicy.

ApplicationRequiresSignedRequests - The request sent by client is not signed while the application requires signed requests

RequestIssueTimeExpired - IssueTime in an SAML2 Authentication Request is expired.

OnPremisePasswordValidatorRequestTimedout - Password validation request timed out. Make sure that Active Directory is available and responding to requests from the agents.

OnPremisePasswordValidatorUnpredictableWebException - An unknown error occurred while processing the response from the Authentication Agent. Retry the request. If it continues to fail, open a support ticket to get more details on the error.

OnPremisePasswordValidatorErrorOccurredOnPrem - The Authentication Agent is unable to validate user's password. Check the agent logs for more info and verify that Active Directory is operating as expected.

OnPremisePasswordValidationEncryptionException - The Authentication Agent is unable to decrypt password.

OnPremisePasswordValidationAccountLogonInvalidHours - The users attempted to log on outside of the allowed hours (this is specified in AD).

OnPremisePasswordValidationTimeSkew - The authentication attempt couldn't be completed due to time skew between the machine running the authentication agent and AD. Fix time sync issues.

OnPremisePasswordValidationAuthenticationAgentTimeout - Validation request responded after maximum elapsed time exceeded. Open a support ticket with the error code, correlation ID, and timestamp to get more details on this error.

DesktopSsoIdentityInTicketIsNotAuthenticated - Kerberos authentication attempt failed.

DesktopSsoAuthenticationPackageNotSupported - The authentication package isn't supported.
