1krb5_init_creds_step - Get the next KDC request for acquiring initial credentials. 2==================================================================================== 3 4.. 5 6.. c:function:: krb5_error_code krb5_init_creds_step(krb5_context context, krb5_init_creds_context ctx, krb5_data * in, krb5_data * out, krb5_data * realm, unsigned int * flags) 7 8.. 9 10 11:param: 12 13 **[in]** **context** - Library context 14 15 **[in]** **ctx** - Initial credentials context 16 17 **[in]** **in** - KDC response (empty on the first call) 18 19 **[out]** **out** - Next KDC request 20 21 **[out]** **realm** - Realm for next KDC request 22 23 **[out]** **flags** - Output flags 24 25 26.. 27 28 29:retval: 30 - 0 Success; otherwise - Kerberos error codes 31 32 33.. 34 35 36 37 38 39 40 41This function constructs the next KDC request in an initial credential exchange, allowing the caller to control the transport of KDC requests and replies. On the first call, *in* should be set to an empty buffer; on subsequent calls, it should be set to the KDC's reply to the previous request. 42 43 44 45If more requests are needed, *flags* will be set to #KRB5_INIT_CREDS_STEP_FLAG_CONTINUE and the next request will be placed in *out* . If no more requests are needed, *flags* will not contain #KRB5_INIT_CREDS_STEP_FLAG_CONTINUE and *out* will be empty. 46 47 48 49If this function returns **KRB5KRB_ERR_RESPONSE_TOO_BIG** , the caller should transmit the next request using TCP rather than UDP. If this function returns any other error, the initial credential exchange has failed. 50 51 52 53 *context* must be the same as the one passed to krb5_init_creds_init() for this initial credentials context. 54 55 56 57 58 59 60 61 62 63 64.. 65 66 67 68 69 70
