NAME

       sasl_client_start - Begin an authentication negotiation

SYNOPSIS

       #include <sasl/sasl.h>

       int sasl_client_start(sasl_conn_t * conn,
		       const char * mechlist,
		       sasl_interact_t ** prompt_need,
		       const char ** clientout,
		       unsigned * clientoutlen,
		       const char ** mech);

DESCRIPTION

       sasl_client_start()  selects  a	mechanism for authentication and starts the authentication session. The mechlist is the list of mechanisms
       the client might like to use. The mechanisms in the list are not necessarily supported by the client or even valid. SASL  determines  which
       of  these to use based upon the security preferences specified earlier. The list of mechanisms is typically a list of mechanisms the server
       supports acquired from a capability request.

       If SASL_INTERACT is returned the library needs some values to be filled in before it can proceed. The prompt_need structure will be  filled
       in with requests. The application should fulfill these requests and call sasl_client_start again with identical parameters (the prompt_need
       parameter will be the same pointer as before but filled in by the application).

       mechlist is a list of mechanisms the server has available. Punctuation if ignored.

       prompt_need is filled in with a list of prompts needed to continue (if necessary).

       clientout and clientoutlen is created. It is the initial client response to send to the server. It is the job of the client to send it over
       the network to the server.  Any protocal specific encoding (such as base64 encoding) necessary needs to be done by the client.

       If the protocol lacks client-send-first capability, then set clientout to NULL.

       If there is no initial client-send, then *clientout will be set to NULL on return.

       mech contains the name of the chosen SASL mechanism (on success)

RETURN VALUE

       sasl_client_start  returns  an  integer	which corresponds to one of the following codes. SASL_CONTINUE indicates sucess and that there are
       more steps needed in the authentication. All other return codes indicate errors and should either be handled or the authentication  session
       should be quit.

CONFORMING TO

       RFC 2222

NAME

       sasl_client_step - Perform a step in the authentication negotiation

SYNOPSIS

       #include <sasl/sasl.h>

       int sasl_client_step(sasl_conn_t *conn,
		      const char *serverin,
		      unsigned serverinlen,
		      sasl_interact_t ** prompt_need,
		      const char ** clientout,
		      unsigned * clientoutlen);

DESCRIPTION

       sasl_client_step()  performs  a	step  in  the  authentication  negotiation.  It  returns SASL_OK if the whole negotiation is sucessful and
       SASL_CONTINUE if this step is ok but at least one more step is needed. A client should not assume an authentication negotiation is  sucess-
       ful just because the server signaled success via protocol (i.e. if the server said ". OK Authentication succeeded" in IMAP sasl_client_step
       should still be called one more time with a serverinlen of zero.

       If SASL_INTERACT is returned the library needs some values to be filled in before it can proceed. The prompt_need structure will be  filled
       in with requests. The application should fulfill these requests and call sasl_client_start again with identical parameters (the prompt_need
       parameter will be the same pointer as before but filled in by the application).

       conn is the SASL connection context

       serverin is the data given by the server (decoded if the protocol encodes requests sent over the wire)

       serverinlen is the length of serverin

       clientout and clientoutlen is created. It is the initial client response to send to the server. It is the job of the client to send it over
       the network to the server.  Any protocal specific encoding (such as base64 encoding) necessary needs to be done by the client.

RETURN VALUE

       sasl_client_step returns an integer which corresponds to one of the following codes. SASL_CONTINUE indicates sucess and that there are more
       steps needed in the authentication. SASL_OK indicates that the authentication is complete. All  other  return  codes  indicate  errors  and
       should either be handled or the authentication session should be quit.
