[xwiki-users] Active Directory: Log on permission to the DC is needed to authenticate

All, I'm working on setting up active directory authentication for a xwiki site but our domain permissions only allow users to log onto certain computers for security reasons. The users do have permission to log onto the server that is hosting XWiki but when they try and authenticate they receive the LDAP data 531 error which means they do not have permission to log onto the workstation. When I add permissions to log onto the domain controller the users are then able to authenticate. Is there any reason that they need local login access to the DC/Is there any way to fix this? Also, when we use the wyiswyg editor the layout becomes skewed; for example the editor overlaps the center section and the bars to the right overlap the editor. Thanks for your help! Sincerely, Matthew Serel
