I'm running FreeNAS 11.3-U1 and haven't yet upgraded to U2.1.
Originally, pre 11.3, I was using simple LDAP to provide users to the system, and samba was using that LDAP based user setup to authenticate. Everything was great until I upgraded to 11.3, and then none of that worked any more. Everything else worked fine, but I could never figure out how to get simple LDAP directory users showing up for samba working again.
If I could figure out how to completely reset everything samba related...
