SYNOPSIS

11       #include <sasl/sasl.h>
12
13       int sasl_server_start(sasl_conn_t * conn,
14                            const char * mech,
15                            const char * clientin,
16                            unsigned * clientinlen,
17                            const char ** serverout,
18                            unsigned * serveroutlen);

DESCRIPTION

21       sasl_server_start() begins the authentication with the mechanism speci‐
22       fied with mech. This fails if the mechanism is not  supported.  SASL_OK
23       is returned if the authentication is complete and the user is authenti‐
24       cated. SASL_CONTINUE is  returned  if  one  or  more  steps  are  still
25       required  in the authentication. All other return values indicate fail‐
26       ure.
27
28
29       conn is the SASL context for this connection
30
31       mech is the mechanism name that the client requested
32
33       clientin is the client initial response, NULL  if  the  protocol  lacks
34       support  for client-send-first or if the other end did not have an ini‐
35       tial send.  Note that no initial client send is distinct from  an  ini‐
36       tial send of a null string, and the protocol MUST account for this dif‐
37       ference.
38
39
40       clientinlen is the length of initial response
41
42       serverout is created by the plugin library. It is  the  initial  server
43       response  to send to the client. This is allocated/freed by the library
44       and it is the job of the client to send it  over  the  network  to  the
45       server.  Also protocol specific encoding (such as base64 encoding) must
46       needs to be done by the server.
47
48       serveroutlen is set to the length of initial server challenge
49

RETURN VALUE

51       sasl_server_start returns an integer which corresponds to  one  of  the
52       SASL  errorcodes.  SASL_OK  indicates  that authentication is completed
53       successfully. SASL_CONTINUE indicates success and that there  are  more
54       steps  needed  in  the  authentication. All other return codes indicate
55       errors and should either  be  handled  or  the  authentication  session
56       should be quit.
