PollModeGrantProcessor Class

Abblix.Oidc.Server​

Abblix.Oidc.Server.Features.BackChannelAuthentication.GrantProcessors​

PollModeGrantProcessor Class​

Handles CIBA poll mode token retrieval at the token endpoint. In poll mode, clients repeatedly poll until authentication completes. Tokens are removed from storage immediately after retrieval to prevent duplicate issuance. Uses atomic try-remove operation to prevent race conditions.

public class PollModeGrantProcessor : Abblix.Oidc.Server.Features.BackChannelAuthentication.Interfaces.IBackChannelGrantProcessor

Inheritance System.Object → PollModeGrantProcessor

Implements IBackChannelGrantProcessor

Constructors​

PollModeGrantProcessor(IBackChannelRequestStorage) Constructor​

Handles CIBA poll mode token retrieval at the token endpoint. In poll mode, clients repeatedly poll until authentication completes. Tokens are removed from storage immediately after retrieval to prevent duplicate issuance. Uses atomic try-remove operation to prevent race conditions.

public PollModeGrantProcessor(Abblix.Oidc.Server.Features.BackChannelAuthentication.Interfaces.IBackChannelRequestStorage storage);

Parameters​

storage IBackChannelRequestStorage​

Storage for backchannel authentication requests.

Methods​

PollModeGrantProcessor.ProcessAuthenticatedRequestAsync(string, BackChannelAuthenticationRequest) Method​

Atomically removes the authentication request from storage and returns its authorized grant. If a concurrent request already consumed the entry, returns an invalid_grant error to prevent duplicate token issuance.

public System.Threading.Tasks.Task<Abblix.Utils.Result<Abblix.Oidc.Server.Endpoints.Token.Interfaces.AuthorizedGrant,Abblix.Oidc.Server.Common.OidcError>> ProcessAuthenticatedRequestAsync(string authenticationRequestId, Abblix.Oidc.Server.Features.BackChannelAuthentication.BackChannelAuthenticationRequest request);

Parameters​

authenticationRequestId System.String​
request BackChannelAuthenticationRequest​

Implements ProcessAuthenticatedRequestAsync(string, BackChannelAuthenticationRequest)

Returns​

System.Threading.Tasks.Task<Abblix.Utils.Result<AuthorizedGrant,OidcError>>

PollModeGrantProcessor.ValidateTokenEndpointAccess() Method​

Poll mode clients are expected to poll the token endpoint, so this always returns null (no error).

public Abblix.Oidc.Server.Common.OidcError? ValidateTokenEndpointAccess();

Implements ValidateTokenEndpointAccess()

Returns​

OidcError
