RE: auditing failed login attempts
Caveat with using ppolicy to sync pwdfailures, etc:
I've failed in my attempts to get both of the following to work at same time:
1) passwords are actually checked (vs anything submitted for password will work)
2) and getting ppolicy pwdfailures to replicate from slaves to the master
Obviously #1 trumps #2.
Perhaps I did something wrong (along with follow up users), but no-one offered any suggestions or pointers, or things are better now.
Just make sure you test bad passwords before you assume 'authentication is working'.
Caveat Emptor.

slapo-auditlog?
slapo-accesslog?
Don't know if you use it, but your security team may like you to use
ppolicy:
