Hi @Dhanush Partha ,
I understand that you are receiving the error, "Unable to test SAML single sign-on."
It sounds like it could be an issue with the user account being unable to SSO. I would recommend assigning different users to the application and seeing if you face the same error. Validate that the user is an Entra ID account user, that the user is not blocked from signing in, and that the user has proper licenses assigned.
I would also recommend making sure that you are signed in with at least a Cloud Application Administrator and follow the debug steps in this article. https://learn.microsoft.com/en-us/entra/identity/enterprise-apps/debug-saml-sso-issues
If you still receive the error and are unable to test after validating the account permissions, feel free to reach out to me at AzCommunity@microsoft.com ("Attn: Marilee Turscak") and include your subscription ID and a link to this thread, and I will gladly help troubleshoot.
