In order to allow chrome to pass credentials to web services linked to ADFS, you can just add the Fqdn of your adfs server to the following chrome policies.
both values are Strings (Reg_SZ)
enter the values without protocol information: myserver.mydomain.com
Note that if you do not use Chrome ADM files to manage the entries via GPO, you can still use the entries by entering the paths manually (as administrator).
The key to create (if you don’t use Gpos) is HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome
