• NAME
  
  sasl_server_start - Begin an authentication negotiation
  
  
• SYNOPSIS
  

  
   #include <sasl/sasl.h>
  
   int sasl_server_start(sasl_conn_t *  conn , 
    		           const char *  mech ,    		           const char *  clientin ,    		           unsigned *  clientinlen ,    		           const char **  serverout ,    		           unsigned *  serveroutlen ); 

• DESCRIPTION
  
  
  sasl_server_start() begins the authentication with the mechanism specified with mech. This
  fails if the mechanism is not supported. SASL_OK is returned if the
  authentication is complete and the user is
  authenticated. SASL_CONTINUE is returned if one or more steps are
  still required in the authentication. All other return values indicate
  failure.
  
  
  
  
  conn
  is the SASL context for this connection
  
  
  
  mech
  is the mechanism name that the client requested
  
  
  
  clientin
  is the client initial response, NULL if the protocol lacks support for
  client-send-first or if the other end did not have an initial send.  Note that
  no initial client send is distinct from an initial send of a null string,
  and the protocol MUST account for this difference.
  
  
  
  
  clientinlen
  is the length of initial response
  
  
  
  serverout
  is created by the plugin library. It is the initial server response to send to the client. This is allocated/freed by the library and it is the job of the client to send it over the network to the server. Also protocol specific encoding (such as base64 encoding) must needs to be done by the server.
  
  
  
  serveroutlen
  is set to the length of initial server challenge
  
  
  
  
  
  
  
  
  
• RETURN VALUE
  
  
  sasl_server_start returns an integer which corresponds to one of the
  SASL errorcodes. SASL_OK indicates that authentication is completed
  successfully. SASL_CONTINUE indicates success 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.
