Document: User from ActiveDirectory can authenticate with previous password after changing password through Crowd.

Note: I would like to bring this to the attention of the doc team. I was confused for a while and thinking that we had a security bug in our hands. Turns out this is a known issue with AD, and there are ways to mitigate how long the old password remains active for: http://support.microsoft.com/kb/906305

• Add an ActiveDirectory in Crowd with Read-Write permissions. I used ldaps://crowd-ad1.sydney.atlassian.com:636 (make sure to install the certificate as mentioned here: https://extranet.atlassian.com/display/CROWD/LDAP+Servers
• Add the directory to an application and set allow all to authenticate = true.
• Verify that you can authenticate with the AD user by going to the Authentication Test
• Go to the Users tab and select the AD user.
• Change the users password
• Go back to the Authentication Test

Expected: User to only be able to authenticate with the new password

Actual: User can authenticate with the new password as well as the old one.
