Account Lockout After One Bad Password

[Enzo]

I'm running Filemaker Server 7 Advanced, patch two, with IWP, and Active Directory authentication. When a user types in a bad password once, their account is immediately locked in AD.

I checked the domain controller logs, and the filemaker server is sending multiple bad passwords to the domain controller within one second. (Even though the user typed their password incorrectly once.)

Has anyone else ran into this? Is there a fix?

Thanks,

Enzo
