Greetings,  I am trying to configure LDAP authentication, but it doesn't appear to work.  I have setup my connection to my AD server and when I test that it tells me the connection is successful.  I then add a user and everytime I get the same error when I try to authenticate:    You have been denied access to the system.  (Error Code 0x6000001) Please verify and re-enter your login information.  Can anyone provide details on what the trick is?  I have tried users, groups, different OUs, Containers, etc...  Nothing works.  I appreciate any tips that gets me going.  Thank you.
