ADAL - Failed to acquire token silently issue

Hi All,

 we have a MultiTenant Application & we are using Microsoft.IdentityModel.Clients.ActiveDirectory version 2.12.0.0. 

when we try to acquire Silent toke  we are getting exception. Below is the Exception -

Microsoft.IdentityModel.Clients.ActiveDirectory.AdalSilentTokenAcquisitionException: Failed to acquire token silently.

Below is the piece of code we have used  to do this -

try
            {
                //Get Auth Context.
                AuthenticationContext authContext = new AuthenticationContext(string.Format(aadInstance, tenantId), new NaiveSessionCache(userObjectID));

                //read certificate from store.
                X509Certificate2 tokenCertificate = GetCertificateFromStore();

                //Get Client Assertion Certificate.
                ClientAssertionCertificate assertionCertificate = new ClientAssertionCertificate(clientId, tokenCertificate);

                //Acuire Silent token.
                AuthenticationResult result = authContext.AcquireTokenSilent(resourceId, assertionCertificate, new UserIdentifier(userObjectID, UserIdentifierType.UniqueId));
                
                //return access token.
                if (result != null && !string.IsNullOrEmpty(result.AccessToken))
                    return result.AccessToken;
                else
                    return null;
            }
            catch (AdalSilentTokenAcquisitionException ex)
            {
                throw ex;
            }

Any help would be much appreciated.

Thanks,

Ritesh
