I am trying to implement Linux workstation authorization with the ldap server built into Zimbra following this guide: UNIX and Windows Accounts in Zimbra LDAP and Zimbra Admin UI 6.0 - Zimbra :: Wiki

The guide went through perfectly fine but I can't actually get the authorization to work on the user workstation, it constantly fails to verify the password. More investigation with Wireshark revealed that it was failing to bind properly giving the "invalidCredentials" error. I have tried using a standalone LDAP server to authorize users and it worked fine. I have double checked all my ACL parameters to see that the server has proper permissions and everything looks in check. I am at a loss at what is causing this.
