Subject: Where is account lockout and password expiry described in the docs?

I've been looking for the formal documentation for account lockout and expiry handling.  There are no references that I can find in 

The only reference in MS-ADTS is in 6.1.5.4 PDC Emulator FSMO Role, which gives the clue that we need to forward all bad passwords to the PDC.  But that leaves a lot of questions, like what to do (what error to
give) if the PDC is offline. 

The only reference in MS-SAMR is to actual enforcement is in .1.5.14.5 Account Lockout Enforcement and Reset, but this is for password change. 

There is also MS-SAMR 3.1.5.13.7.1 SamValidateAuthentication but nothing I could find indicates how this fits in to the broader picture. 

MS-NRPC refers to this as passthough authentication, and MS-NLMP does not describe expiry or lockout at all.

Where can I find a clear description of how to implement account lockout (for bad passwords) and expiry?

Thanks,

Andrew Bartlett
