There were several problems:
- A cut-n-paste error where the wrong value was being considered when
an account was administratively unlocked.
- An off-by-one error where LDAP got one extra bind attempt.
- krbPwdPolicyReference wasn't being retrieved as a virtual attribute so
only the global_policy was used.
- The lockout duration wasn't examined in the context of too many failed
logins so wasn't being applied properly.
- Lockout duration wasn't used properly so a user was effectively unlocked
when the failure interval expired.
- krbLastFailedAuth and krbLoginFailedCount are no longer updated past
max failures.

Ther3 are two global ipaConfig options to disable undesirable writes that
have performance impact.
The "KDC:Disable Last Success" will disable writing back to ldap the last
successful AS Request time (successful kinit)
The "KDC:Disable Lockout" will disable completely writing back lockout
related data. This means lockout policies will stop working.

On a failed bind this will update krbLoginFailedCount and krbLastFailedAuth
and will potentially fail the bind altogether.
On a successful bind it will zero krbLoginFailedCount and set
krbLastSuccessfulAuth.
This will also enforce locked-out accounts.
See http://k5wiki.kerberos.org/wiki/Projects/Lockout for details on
kerberos lockout.
