Re: [Samba] samba bad password count reset between logins (not loaded from login_cache.tdb)




Hi Denis,

Thanks for your suggestion

When I looked into Samba4 AD, I figured it would take too much effort to port our infrastructure to it, seemingly without benefits

We already have a quite extensive network architecture with OpenLDAP acting as a LDAP server. Samba4 AD seems to require its own LDAP implementation (and some more quirks IIRC).
There's also the additional DNS configuration necessary.

Our network fulfills our needs at the moment with a PDC. The migration of our Samba user data to LDAP is merely to simplify administration.

Hi Daryl,

bad password lockout works fine in Samba AD mode. Is there a technical reason for you to keep on using PDC NT4 mode? In AD mode, you'll also get a LDAP, and it will be much easier to setup and manage!

By the way, it is not necessary to be in PDC LDAP backend to migration to Samba AD.

Cheers,

Denis
