[Samba] Still confused about Kerberos password expiry

[jimc]

I know this is going to come as a shock. I have spent hours in 
samba-tool. Had I found an answer there I would not have subjected 
myself to the condescension of the list.

I haven't found an example there for how to properly set up a dns zone 
either.

Where is the real documentation? How do I learn what the options are to 
the samba-tool commands that demand them but won't tell me what they are?

Am I really the only person in the whole world who is frustrated with 
the state of the documentation?

Yes?

I guess I'm just too stupid to learn your product.
