Google Chrome

Configuring Chrome to work with Kerberos on Windows can be done in more than one way.
By default, Chrome uses the same registry settings as Edge/Internet Explorer on Windows to determine if sending Kerberos tickets to a site is allowed. 
This means that you usually don't need to configure Chrome explicitly if the site has been added to the Local Intranet Zone list.

Chrome can also be configured to use its own list of URLs that it will respond with Kerberos ticket to.
AuthServerAllowlist (earlier called AuthServerWhitelist) is deployed through Active Directory Group Policy and will override Internet Explorer settings for Chrome.

Chrome policy

To check whether your Chrome uses the AuthServerAllowlist, take a look at URL: chrome://policy 

If Chrome policies state "No policies set," Chrome on Windows will instead use Local Intranet Zone. Your site must be added to that list for Chrome to work with Kerberos on Windows. Chrome on other operating systems requires policies to work with Kerberos.

When defined, Chrome policies override the Windows Local Intranet Zone List.
Refer to and for details.


On OS X you may run commands below with your domain names in a terminal window to configure Chrome. Restart Chrome afterward. The first command removes the deprecated name AuthServerWhitelistthat was replaced by AuthServerAllowlistin 2020:
defaults delete AuthServerWhitelist
defaults write AuthServerAllowlist ","

Policies that may affect how Chrome and Kerberos works:

  • AuthSchemes: Specifies which HTTP authentication schemes are supported by Google Chrome. Possible values are 'basic', 'digest', 'ntlm' and 'negotiate'. Kerberos requires 'negotiate.' If this policy is left unset, all four schemes will be available.     

  • AuthServerAllowlist: Specifies which servers should be whitelisted for integrated authentication. Integrated authentication is only enabled when Google Chrome receives an authentication challenge from a proxy or from a server that is in this permitted list, e.g., * or, must be added. Separate multiple server names with commas. When unset,  Chrome will try to detect if a server is on the Intranet, and only then will it respond to IWA requests. IWA requests from non-intranet servers will be ignored by Chrome. 

Using short-form URLs

Note that when accessing the application using the short format URL (http://issues), browsers will still look for an SPN in the FQDN format (

By default, Internet Explorer treats short format URLs and sites as they were in Local Intranet Zone with the "Include all local (intranet) sites not listed in other zones" checked. In this case, sites do not have to be added to IE Local Intranet Zone for Kerberos to work with Internet Explorer.

Chrome will need to have the site added to AuthServerAllowList to work with Kerberos.
