    NAME

    sasl_client_step - acquire an auxiliary property context
     
    

    SYNOPSIS

    cc [ flag ... ] file ... -lsasl   [ library ... ]
    #include <sasl/sasl.h>
    
    int sasl_client_step(sasl_conn_t *conn, const char *serverin,
        sasl_interact_t **unsigned serverinlen, prompt_need,
        const char **clientout, sasl_interact_t **unsigned *clientoutlen);
    

     

    DESCRIPTION

    Use the sasl_client_step() interface performs a step in the authentication negotiation. sasl_client_step() returns SASL_OK if the complete negotiation is successful. If the negotiation on step is completed successfuly, but at least one more step is required, sasl_client_step() returns SASL_CONTINUE. A client should not assume an authentication negotiaion is successful because the server signaled success through the protocol. For example, if the server signaled OK Authentication succeeded in IMAP, sasl_client_step() should be called one more time with a serverinlen of zero.

    If a call to sasl_client_step() returns SASL_INTERACT, the library requires some values before sasl_client_step() can proceed. The prompt_need structure will be filled with the requests. The application should fulfull these requests and call sasl_client_step() again with identical parameters. The prompt_need parameter will be the same pointer as before, but it will have been filled in by the application.  

    PARAMETERS

    conn

    The SASL connection context.

    serverin

    The data given by the server. The data is decoded if the protocol encodes requests sent over the wire.

    serverinlen

    The length of the serverin.

    clientout
    clientoutlen

    clientout and clientoutlen are created. They contain the initial client response to send to the server. It is the job of the client to send them over the network to the server. Any protocol specific encodingthat is necessary, for example base64 encoding, must be done by the client.

    prompt_need

    A list of prompts that are needed to continue, if necessary.

     

    RETURN VALUES

    sasl_client_step() returns an integer that corresponds to a SASL error code.  

    ERRORS

    SASL_OK

    The call to sasl_client_start() was successful. Authentication is complete.

    SASL_CONTINUE

    The call to sasl_client_start() was successful, but at least one more step is required for authentication.

    SASL_INTERACT

    The library requires some values before sasl_client_step() can proceed.

    All other error codes indicate an error situation that must be handled, or the authentication session should be quit. See sasl_errors(3SASL) for information on SASL error codes.
