Splunk DB Connect 2: Why am I getting "This driver is not configured for integrated authentication" trying to validate connection with my SQL database?


Hi All,

I have installed Splunk DB Connect 2 and am trying to connect to my SQL Server database. Both Splunk and SQL Server are running on my local machine. I followed the DB Connect 2 instructions and am trying to use the Windows Authentication process.

I have created an Identity and Connection, but when I validate the connection, I get the "Internal Server Error" message. I can read the log in Splunk by running the code index=_internal source=*dbx2.log and I get this message:

Validating connection with URL [jdbc:sqlserver://localhost:1433;databaseName=northwind;selectMethod=cursor;integratedSecurity=true] failed: java.sql.SQLException:java.sql.SQLException: Cannot create PoolableConnectionFactory (This driver is not configured for integrated authentication.

I am not sure what this means as I am certain I followed the steps to install the correct library so that it will use integrated authentication.

Any thoughts would be appreciated.

Update PATH environment variable with folder location where sqljdbc_auth.dll is located.

After this you would observe another issue. Splunk would not pick right user name from the connection. In my case it picked [host name]$

Use jTDS driver.
Download it from [jTDS][1].
Unpack the zip and copy jtds-1.3.1.jar to C:\Program Files\Splunk\etc\apps\splunk_app_db_connect\bin\lib
Restart splunk server

[1]:,**SECOND :**
You should use jTDS driver to resolve this issue. Looks like Micorsoft Driver is not supported by Splunk for this scenario.

I tried it with good configuration but I observed splunk picking wrong user name and not the user name provided in the connections (splunk server host name) while connecting to SQL Server.

Download jTDS drivers from :

Unzip the packages and place the jtds-1.3.1.jar in C:\Program Files\Splunk\etc\apps\splunk_app_db_connect\bin\lib

To resolve your error : Makesure that the PATH variable is set to folder where sqljdbc_auth.dll exists ( careful about x86 and x64).
After doing this, you would run into another issue as described above.


Thanks Avsnarayan, this solution worked fort me as well. Splunk DB connect is installed on a RHEL 6.7 server and was trying to connect to MS SQL server on Windows. the jTDS driver worked over the driver available from Microsoft (still giving errors).

hahaha yes indeed the sales rep would - god love 'em:)
Actually just a bit more on this, when i click the query tab in explorer from the validated connection I can run a query and display data from the database so i think this is good enough. DB Connect 2 is a little bit different to DB1 but I may be able to connect the query output to some lookups and so forth to "enrich" the data as i have done previously in DB1.
All good. Thanks.


Thanks for the info. I got past this issue by enabling the sql server sa account and changing from the " with windows authentication" driver to the one without. The connection now validates. Unfortunately I am using the "free" license and get the error in the log that says this license can't run "the requested action". So my demo tomorrow will not include a database connection part.
Thanks again.


Hi Binway,

I had a similar situation. Was using Windows authentication, but it didn't work. Then I try my luck by creating a new SA account. It works perfectly. Thank you.

Splunk or SQL Server producing the error? If Splunk, I'm sure your sales rep would love to talk about a temp license for a demo. (If it goes well they could get sales)
