FME Flow: 2025.1 BETA
Updating the Web Browser Configuration
Depending on the browser used to access the FME Flow Web User Interface, additional configuration steps may be required for Integrated Windows Authentication (single sign-on).

In most common Windows domain configurations, no additional configuration is necessary. However, if a user is unable to use single sign-on with FME Flow, check the following:
- Open 'Internet Options' from the Start menu.
- On the 'Security' tab, select 'Local intranet'.
- If FME Flow is not a part of the local intranet, add it to the list of local intranet sites. To do so, click Sites -> Advanced, then add the site address (for example, http://fmeflow.domain.net).
- On the 'Security' tab, select 'Local intranet' and click 'Custom level...'.
- Ensure that under User Authentication -> Login, 'Automatic logon only in Intranet zone' is selected.
- On the 'Advanced' tab, ensure that Security -> Enable Integrated Windows Authentication is checked.
- Restart the browser.

Single sign-on is supported in Chrome versions 8 and later.
In most common Windows domain configurations, no additional configuration is necessary. However, if a user is unable to use single sign-on with FME Flow, perform the same steps outlined under Microsoft Edge.

Single sign-on is supported on all versions of Firefox.
To enable single sign-on in Firefox:
- In the address bar, type about:config. Accept the warning if one appears.
- In the search bar, type network.negotiate.
- Select the preference 'network.negotiate-auth.trusted-uris', and double-click it to modify its value.
- Enter FME Flow's site address (for example, http://fmeflow.domain.net), and click OK. Do not specify a port or path. Multiple site addresses can be listed, separated by a comma (,).
- If using a private browsing tab, search for network.auth.private-browsing-sso.
- Double-click on network.auth.private-browsing-sso to change the Value to true.
- Restart the browser.

Single sign-on is currently not supported on these browsers.
