Hi, 

We setup the Tableau Server 2026 with Local authentication, and in the process of hosting the site externally, for security reasons, we need to have MFA for the login process. I don't see an option for MFA. This project is for external customers, who are not in our domain, and will not be added to the domain. 

 

What options do we have for MFA or any additional security options than just username + password.

    Just an additional comment on the Identity Pool part as it is easy to mix up things. 

    Identity Pool is a pair of 1) an identity store and 2) an identity provider. 

    identity store can be local or AD/LDAD, and identity provider always and only OIDC. 

    But the Identity Pool identity store is constrained by your original identity store defined during Tableau Server installation. 

    If identity store local then Identity Pool identity store can only be local (same or new) 

    If identity store AD/LDAP then Identity Pool identity store can only be  AD/LDAP (same!) 

    It is pretty cool but tedious to configure as there is no tsm command or GUI to configure it. it is all through REST API calls only. 

    Then your Tableau login page will have an additional button, for example External users. 

    The internal users can continue to use Local authentication or SAML, it is totally independant.

    Just an additional comment on the Identity Pool part as it is easy to mix up things. Identity Pool is a pair of 1) an identity store and 2) an identity provider.

    It was a very good idea from Tableau, but Tableau didn't further develop this feature since 3 years.

My company security team audited the Tableau and found, that specific password policy is not possible to be configured: 

 

New passwords checked against the history of the last 5 passwords and rejected if there is a match

 

Can we request to add such password history check feature in Tableau Server Cloud?  

Extend password policy with history

    Hi, unfortunatelly not possible with local auth, you will need to use an external Idp (SAML). 

     

    I suggest you to create an idea for this:

Hello, 

 

My question on the topic detailed below is : is this the expected behavior on Tableau Server or is there something to investigate? 

  

On Tableau Desktop, when you have a table with lots of values, the header values are always on sight even if the number of underlining rows is much higher than the number of rows you can see immediately. To illustrate, you can see

Austria here even if the formatting is in the Middle, and that the middle of that row is much lower in the sheet :Header values visible in Desktop but not on Server

 

When publishing on server, no matter what the formatting is, the behavior is not the same. I.e. it will only show the value if you are viewing the top, middle or bottom of that row's results depending on your formatting choice :

    Unfortunately that has always been a limitation of Server/Cloud text tables. I prefer Desktop's behavior. You would need to add a unique hidden column like customer ID to the left of country to get it to appear on every row. But that prevents convenient selection by country.Unfortunately that has always been a limitation of Server/Cloud text tables. I prefer Desktop's behavior.

I am using the Tableau MCP get-view-image Tool. Is there a way to download an image with a set filter applied when using a set as a filter on a dashboard? It appears that there is no way to apply a set filter using the REST API View Filter, so I am asking if there is a workaround.

    Hey, I ran into the same thing. The REST API view filters (and the MCP tool that uses them) only work with regular fields, not sets. One workaround that worked for me was to filter on the underlying field that the set is built from and just pass the member values. If that doesn’t fit, creating a custom view with the set already applied and downloading that image is another option. Hope that helps.

I've converted my Tableau Repository info into a Tableau Data Source for our analysts to use (Collect Data with the Tableau Server Repository), but I'm confused about how the 'device_type' field is calculated. The data dictionary is here: Workgroups Database.

 

It shows about half of the views to be accesses by a user/device type of 'Tablet', which can't be true since only perhaps 3% of our users use a tablet or phone to view our visuals.

 

Can anyone help with the interpretation/calculation of this field?

 

Thanks!

    Hi Andy!

     

    From what I understand from the documentation, the "device_type" is not what type of device is viewing the dashboard, it's for what type of dashboard was being presented to the client. The explanation for "device_type" is "DSD device type detected" - "DSD" stands for "device-specific dashboard" - this is the type of dashboard layout created in Tableau Desktop. I do not believe this field will track what device was viewing the page, it will only show what dashboard was offered to the user. you can read more about Device Specific Dashboards here: Design dashboards that shine on any device in Tableau 10 | Tableau Software

     

    Hope this helps!

Hi,  

I'm trying to embed a Tableau Dashboard into a Sharepoint page. I have ironed out connection and permissions issues and all is now working well.. expcept.. when somebody first lands on the Sharepoint page instead of seeing the dashboard they see a "Sign in to Tableau" server message / button. If they press this, the dashboard is then displayed, without the need for them to enter any further credetials. So its not a huge issue, but also not a great user experience. Does anybody know a way I can prevent the Tableau sign in page stage please?

    This sounds like an authentication/session issue. Check your Tableau SSO or Connected Apps configuration, and also make sure browser third-party cookies aren’t blocking the Tableau session. Since clicking “Sign in” immediately works without credentials, the user is likely already authenticated, but Tableau isn’t recognizing the session on initial load.

Hi,  

 

We recently suffered an outage at the data centre hosting Tableau Server on Ubuntu. It was brought back up but the backups started failing due to lack of space. We added an extra 25GB but it didn't help.  

 

I ran some checks on the disk storage and found our /extracts folder is using 46GB: 

 

77G     /var 

46G     /var/opt/tableau/tableau_server/data/tabsvc/dataengine 

43G     /var/opt/tableau/tableau_server/data/tabsvc/dataengine/extract 

 

However, according to the Server Space reports in Tableau, the entire server itself is only using 32B, of which about 20GB is extracts. Claude has suggested we have a bloating extracts folder because the extracts being refreshed during the outage were interrupted mid-write, and so haven't been removed cleanly on the next extract refresh. 

 

I'm looking for a way of manually clearing out this folder to remove unnecessary space without affecting existing current extracts. 

 

Thanks

    Hi @technical Department

     

    orphan or duplicate extracts can occur but currently it is a just a theory in your case. 

    What Tableau Server do you have ? If >= 2025.1, you have recycle bin feature so you should try to empty it first. 

    - About orphans / duplicates, basically any hyper extract file present in dataengine > extract folder but not present in postgres repository table "

    extracts " (identified by its "descriptor" value/folder, can be deleted. 

    - Similary any extract record reference present in postgres repository table "

    extracts " with datasource_id null AND workbook_id null

    , can be deleted from the dataengine > extract folder. But backgrounder is supposed to delete those automatically.

    It is a it technical topic so take your time to audit your instance before doing any change and have a backup strategy in place. 

    And if any doubt, you can always open a Tableau Support case.
