Ksetup:listrealmflags

Published: May 25, 2011

Updated: April 17, 2012

Applies To: Windows Server 2008 R2

Lists the available realm flags that can be reported by ksetup. For examples of how this command can be used, see Examples.

ksetup /listrealmflags

The realm flags specify additional features of a non-Windows-based Kerberos realm. Computers that are running Windows Server 2003, Windows Server 2008, or Windows Server 2008 R2 can use a non-Windows-based Kerberos server to administer authentication instead of using a domain that is running a Windows Server operating system. These systems participate in a Kerberos realm instead of a Windows domain. This entry establishes the features of the realm. The following table describes each.

 

Value Realm flag Description

0xF

All

All realm flags are set.

0x00

None

No realm flags are set, and no additional features are enabled.

0x01

SendAddress

The IP address will be included within the ticket-granting tickets.

0x02

TcpSupported

The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) are supported in this realm.

0x04

Delegate

Everyone in this realm is trusted for delegation.

0x08

NcSupported

This realm supports name canonicalization, which allows for DNS and realm naming standards.

0x80

RC4

This realm supports RC4 encryption to enable cross-realm trust, which allows for the use of TLS.

Realm flags are stored in the registry in HKLM\SYSTEM\CurrentControlSet\Control\Lsa\Kerberos\Domains\Realm-name. This entry does not exist in the registry by default. You can use the Ksetup:addrealmflags command to populate the registry.

List the known realm flags on this computer:

ksetup /listrealmflags

Set the available realm flags that Ksetup does not know by typing either of the following commands at the command line:

ksetup /setrealmflags CORP.CONTOSO.COM sendaddress tcpsupported delete ncsupported
ksetup /setrealmflags CORP.CONTOSO.COM 0xF
