I would remove `rtrim_char(realm, '\"’);` from this block and keep the if 
condition as-is, since realm is not used later.

Why don’t we do like this:
+                    if (realm == NULL) {
+                        pa_log_error("realm not provided");
+                        goto error;
+                    } else if (nonce == NULL) {
+                        pa_log_error("nonce not provided");
+                        goto error;
+                    }
