• Hudson 1.324
• Hudson Active Directory plugin 1.15

The Security is activated.
"Active Directory" is selected.
Permissions are set "Matrix Based".

If an Active Directory User is added, the user has to log on with his user id
written in the same way it is written in the configuration pages.
If on the Hudson Management pages a user id is written as "YourUserID", the
user cannot log on as i.e. "youruserid" or "YOURUSERID" or "YourUserId"
or "YourUserid". He has to type exactly the same: "YourUserID". Otherwise he
gets the error that no read permission is granted.
For Windows, a User ID is never case sensitive. so logging on should not fail.
