An update is available that introduces the NO_AUTH_REQUIRED flag to the UserAccountControl property in Windows Server 2003 and in Windows 2000

This article describes an update to the UserAccountControl property in Microsoft Windows Server 2003 and in Microsoft Windows 2000. This update introduces the following new flag to the property:
When you use Windows Server 2003 or Windows 2000 as a Kerberos Key Distribution Center (KDC) in a mixed environment, such as an environment that has Windows and Unix servers, the KDC adds Privilege Attribute Certificate (PAC) information to a service ticket. If you do not want to add PAC information to a service ticket for a user who is in Active Directory, you can set the NO_AUTH_DATA_REQUIRED flag for the user account after you install the update.
Flag Hexadecimal value Decimal value -------------------------------------------------------- NO_AUTH_DATA_REQUIRED 0x2000000 33554432
You may want to prevent PAC information from being added to service tickets in situations where the increased size of the service ticket causes issues with programs that use either the User Datagram Protocol (UDP) or remote procedure call (RPC) functionality. A PAC is large, and can increase the size of a ticket more than 500 percent. Tickets that do not have a PAC are approximately 240 bytes. Tickets that have a simple PAC may be approximately 1,200 bytes. Additionally, some services do not understand PAC information. If a PAC is present, services that do not understand the PAC information ignore it.
In a mixed Unix and Windows environment that uses a version of Kerberos that is one or two versions earlier than the current version, ticket requests may not work when a user is a member of many groups in Active Directory. This issue occurs if the PAC information that is added to the ticket increases the size of the ticket to more than the UDP limit of 2,000 bytes. In this situation, ticket requests fail for earlier Unix clients that cannot use TCP.
Because this update applies to Active Directory account properties, install this update on domain controllers. You do not have to install this update on workstations or member servers.
