Hi, I have been using a Python client script to do the authentication in our Linux environment and it’s working properly. Now I need to write a C program to do the authentication and I am choosing Cyrus 2.1.27. After installation, I ran pluginviewer and it showed: Installed and properly configured SASL (client side) mechanisms are: GS2-IAKERB GS2-KRB5 GSSAPI DIGEST-MD5 EXTERNAL CRAM-MD5 PLAIN ANONYMOUS Available SASL (client side) mechanisms matching your criteria are: GS2-IAKERB GS2-KRB5 GSSAPI DIGEST-MD5 EXTERNAL CRAM-MD5 PLAIN ANONYMOUS So I think the installation is OK. But after more than one week of trying, I am not able to make it work. Currently I got “generic failure” error message from the sasl_client_step. I will be appreciated if someone can send me a sample client program using GSSAPI mechanism. Below is my code: int result; const char *data; unsigned len; const char *sasl_impl, *sasl_ver; sasl_interact_t *interactions = NULL; sasl_conn_t *conn; const char *chosenmech; char buf[2048]; sasl_security_properties_t secprops = {56, 256, 2048, SASL_SEC_PASS_CREDENTIALS, NULL, NULL };
sasl_callback_t callbacks[] = { { SASL_CB_AUTHNAME, NULL, NULL }, { SASL_CB_PASS, NULL, NULL }, { SASL_CB_LIST_END, NULL, NULL }}; result = sasl_client_init(callbacks); result = sasl_client_new("HTTP", "SCVIMOPXJDAPP01.INTEL.COM", NULL, NULL, NULL, callbacks, SASL_SUCCESS_DATA, &conn);
sasl_setprop(conn, SASL_SEC_PROPS, &secprops); result=sasl_client_start(conn, "GSSAPI", &interactions, &data, &len, &chosenmech); result = sasl_client_step(conn, NULL, NULL, NULL, &data, &len); while (result == SASL_CONTINUE) { strcpy(buf, data); data=""> result = sasl_client_step(conn, buf, len, NULL, &data, &len);
} After the while loop, the result is -1 (generic failure). Thanks, Jan |
