Synology NAS Multiple Domains

I have a Synology Diskstation DS1515+.  I've joined it to one domain A and I can give any domain A users access to any folders I create.  I have a second domain B that has a full trust.  Currently, any user from domain B doesn't have access to any of the folders and I can't see where to give it access.

Is it possible to select users from the domain B to give access?  When I set permissions on the folders, I can only search the current domain, which is domain A.

Maybe this will help. You might give them a call to see if there is a way to do it through the web interface.

couldn't do it through the web interface. I had to logon the the synology box using SSH and edit the /usr/syno/etc/smb.conf file using vi.

I no longer use the web interface to change security/permissions on the shares, I just edit the smb.conf file.

This post show what you need to do:
This is some info on synology/linux SSH commands available:
And this is help on using vi (errgghh):

Note that to add a user to the list you use the format: <domain>\<username>
But for user groups you prefix the domain with an "@": @<domain>\<username>

We got it working. We had to rejoin the domain after flushing all of the caches in the system settings.
