Secure Store Serviceapp + sql servicer in nontrusted domain

Hi,

I have situation where sql server is hosted in nontrusted domain, and i need to create SecureStoreService App using sql authentication...

Well, i set the sql authentication option, name, password...new application pool with valid serviceaccount. Creation fails and logs are as follows:

Secure Store                      f6jt    High        Provisioning done for SecureStoreServiceDatabase.
Secure Store                      esi5    High        Granting user TEST\sp_serviceapps access to database.
Database                          880i    High        System.Data.SqlClient.SqlException: Windows NT user or group 'TEST\sp_serviceapps' not found. Check the name again.

So even thou sql authentication is checked, it tries to grant database access to domain account, and in this situation sql server know nothing about domain of SP server.

Any ideas or workarounds?

All other serviceapps are running just fine.
