I do hope that '<LONG-DOMAIN>' is the dns domain in uppercase

Are you aware that password complexity is in AD ?

You should remove the two lines above, there are not needed and only
slow things down

You like living dangerously, still using NTLMv1

Are you using a self compiled version of Samba ? or are you using a
Samba package that uses the MIT kdc ?
If the latter, you should be aware that using MIT is still regarded as
experimental and shouldn't be used in production.

Finally, you are using a DC as a fileserver, this is not recommended,
but if you do, you can only set the permissions on the share from
Windows. This means that your shares can only look like this:

[groups]
    comment = Shared directories of groups you are member in.
    path = /home/groups
    read only = No

You also need to read this:
