OK.

Final word back from NetApp - the storage guy brought in their AD team: If this 
is occurring then your setup is incorrect and you need to raise a support call.

There should never be a need to set that option, based on what you have shared 
as your configuration.

Currently yes.

They were joined to Forest 1 DomainB. The error is when trying to map from a 
server in Forest2  DomainA. There's a trust at that level as well, if that 
matters.

His response:

OK, it's guesswork at this stage but I want to suggest that when they ran CIFS 
setup on the controllers they selected Option 4. That suggests they did not 
join the controllers to the domain and are using some LDAP/NIS authentication 
mechanism and therefore, yes, the controllers are suddenly not Windows boxes & 
members of the domain, but are, sadly, probably exposing CIFS and NFS in the 
same volume (perfectly supported and legal etc) but not what the Windows 
clients prefer to play with......... Check with them, are the controllers (or 
the VFilers (they'll know what you mean)) ON the domain..... If they are then 
you shouldn't need the setting you specify (even with the old Windows 2003 
clients) but if the controllers are NOT part of the domain then you're dealing 
with "3rd party" and will probably need that setting. That would be time for an 
infrastructure review to understand why Windows SERVER clients are accessing 
files off a NetApp NAS when that NAS is not inside the home forest, or at least 
a trusted Windows forest.

This is what a senior NetApp engineer says:

You're not dealing with storage as a matter of fact. We natively join the 
domain and look like a Windows box - for the most part. Question to ask them 
before I answer you. DFL of AD. Version on OnTAP on the storage and Windows 
version of the client devices. I'll get back to you when near a big keyboard 
and armed with the answer i those questions.

First pass? Old information. Probably no longer accurate.

So...what are the answers to his questions? :)

I wouldn't do that.

But let me check with a netapp guy.

I am being asked to enable the setting "Send unencrypted password to 
third-party SMB servers" so we can map Windows Servers to NetApp CIFS shares. 
This thread shows it worked for him:
https://communities.netapp.com/thread/24037

Anyone here have any experience with NetApp, CIFS and Windows servers?
