If you have ldap authentication setup and attempt to login as one of the ldap users with a bad password then agile makes two attempts to connect and causes the users account to be locked out in Active Directory before the domain group policies limit. In other words if your group policy says accounts should be locked out after 3 failed attempts you will actually get locked out if you put in the wrong password in Agile just twice because it tries 2 times for each, so four tries with just two failed attempts.
