@Rahul Kaim All the supported WIASupportedUserAgents are listed here: https://learn.microsoft.com/en-us/windows-server/identity/ad-fs/operations/configure-ad-fs-browser-wia. If you have already tried all the agents in this list and still facing the issue, you can choose to go with one of the below options:
- Use Pass-Through Authentication with Seamless Single Signon. Refer to https://learn.microsoft.com/en-us/azure/active-directory/hybrid/how-to-connect-sso for more details.
- Use Primary Refresh Token (PRT) to facilitate Seamless SSO. This can be achieved by using Azure AD join and Hybrid Azure AD Join. As you are using ADFS, you have on-prem identities present, I would suggest you to go with Hybrid Azure AD Join if you are choosing to go with PRT for SSO. There are 2 ways to configure it, please refer to below documents for more detail.
Configure hybrid Azure Active Directory join for federated domains
Configure hybrid Azure Active Directory join for managed domains
