Freenas as Active Directory Member - samba share access when domain controller is offline

Hi,

I added Freenas as a domain member to a Windows Server 2012 r2 domain controller without problems.
Would like to have access to the samba shares using the active directory permissions when the domain controller is offline.
Can Freenas use something like "cashed credentials" so the shares can be accessed when the domain controller is offline?

Thanks,
Tim
