[SSSD-users] Question about AD authentication and trusts

Hi, Can anyone confirm for me if SSSD supports authentication of users belonging to a trusted domain via an AD controller in the trusting domain? ie. A user attempts to log in as fred(a)test1.example.com on a client machine running SSSD, where SSSD has joined a domain test2.example.com and there is a 2-way forest trust between both domains. Is this supported? I've been trying to do so and so far it hasn't been working. For the record, my setup is: AD controller domain test1: Windows server 2012 R2 AD controller domain test2: Windows server 2012 R2 Ubuntu 14.04 client running SSSD 1.12.5 Thanks, Guy
