# OAuth with Snowflake – ODBC Driver Version Issue

**Symptom**\
When connecting to Snowflake using OAuth, you may encounter the following error:

```
SQLSTATE[28000] SQLDriverConnect: 390309 The user you were trying to authenticate as differs from the user tied to the access token.
```

This can occur if the Snowflake ODBC driver version **3.14.0** is being used for OAuth authentication. This particular driver version has been observed to cause OAuth authentication failures in some environments.

**Cause**\
The Snowflake ODBC driver version 3.14.0 has an issue where OAuth connections may not correctly handle the user associated with the access token, resulting in authentication failures.

**Resolution**\
Revert the Snowflake ODBC driver to **3.5.0** (or another earlier stable version) when using OAuth authentication with WriteBackExtreme.\
After downgrading the driver, retry the connection - the error should no longer occur.

**Notes**

* This is related to the Snowflake ODBC driver itself, not to WriteBackExtreme.
* Always ensure the ODBC driver version you select is compatible with your Snowflake setup and OAuth configuration.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.infotopics.com/writebackextreme/troubleshooting-and-faq/database-error/oauth-with-snowflake-odbc-driver-version-issue.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
