Translating a Service Name into GSS-API Format

The first task that client_establish_context() performs is to translate the service name string to internal GSS-API format by using gss_import_name().

Example 5-3  client_establish_context() – Translate Service Name
     * Import the name into target_name.  Use send_tok to save
     * local variable space.

     send_tok.value = service_name;
     send_tok.length = strlen(service_name) + 1;
     maj_stat = gss_import_name(&min_stat, &send_tok,
                        (gss_OID) GSS_C_NT_HOSTBASED_SERVICE, &target_name);
     if (maj_stat != GSS_S_COMPLETE) {
          display_status("parsing name", maj_stat, min_stat);
          return -1;

gss_import_name() takes the name of the service, which is stored in an opaque GSS_API buffer send_tok, and converts the string to the GSS_API internal name target_name. send_tok is used to save space instead of declaring a new gss_buffer_desc. The third argument is a gss_OID type that indicates the send_tok name format. This example uses GSS_C_NT_HOSTBASED_SERVICE, which means a service of the format service@host. See Name Types for other possible values for this argument.
