KLIST

Display a list of currently cached Kerberos tickets.

Syntax
      klist [command]

commands:
   tickets [-lh logonID.highpart] [-li logonID.lowpart]
       tgt [-lh logonID.highpart] [-li logonID.lowpart]
     purge [-lh logonID.highpart] [-li logonID.lowpart]
    sessions [-lh logonID.highpart] [-li logonID.lowpart]
   kcd_cache [-lh logonID.highpart] [-li logonID.lowpart]
     get SPN [-lh logonID.highpart] [-li logonID.lowpart] [-kdcoptions options] [-cachecoptions options]
   add_bind  Domain DC
   query_bind 
   purge_bind
   cloud_debug

Key
   -lh 	Denotes the high part of the user's locally unique identifier (LUID), expressed in hex.
   -li 	Denotes the low part of the user's locally unique identifier (LUID), expressed in hexadecimal.
             If neither –lh nor –li are present, the command defaults to the LUID of the currently signed in user.

   tickets      List the currently cached ticket-granting-tickets (TGTs), and service tickets of the specified logon session.
                This is the default option.

   tgt          Display the initial Kerberos TGT.
   purge        Delete all the tickets of the specified logon session.
   sessions     Display a list of logon sessions on this computer.
   kcd_cache    Display the Kerberos constrained delegation cache information.
   get          Allows you to request a ticket to the target computer specified by the service principal name (SPN).
   add_bind 	Allows you to specify a preferred domain controller for Kerberos authentication.
   query_bind   Display a list of cached preferred domain controllers for each domain that Kerberos has contacted.
   purge_bind   Remove the cached preferred domain controllers for the domains specified.
   kdcoptions   Display the Key Distribution Center (KDC) options specified in RFC 4120.
   /? 	      Display Help.

If no parameters are provided, klist retrieves all the tickets for the currently logged on user.

Each LogonId is divided into two sections, high-part and low-part, separated with a colon ':'
for example:
HighPart:LowPart
0:0x3e7

Domain joined machines obtain Kerberos tickets under two sessions, identified below along with the Low Part of the LogonId. These two accounts will always use the same Low Part LogonId. They should never change.

Output

tickets - Displays the following attributes of all cached tickets:

LogonID: The LUID.
Client: The concatenation of the client name and the domain name of the client.
Server: The concatenation of the service name and the domain name of the service.
KerbTicket Encryption Type: The encryption type that is used to encrypt the Kerberos ticket.
Ticket Flags: The Kerberos ticket flags. Start Time: The time from which the ticket is valid.
End Time: The time the ticket becomes no longer valid. When a ticket is past this time, it can no longer be used to authenticate to a service or be used for renewal.
Renew Time: The time that a new initial authentication is required.
Session Key Type: The encryption algorithm that is used for the session key.

tgt - Displays the following attributes for the currently cached ticket:

LogonID: Identified in hex.
ServiceName: krbtgt
TargetName SPN: krbtgt
DomainName: Name of the domain that issues the TGT.
TargetDomainName: Domain that the TGT is issued to.
AltTargetDomainName: Domain that the TGT is issued to.
Ticket Flags: Address and target actions and type.
Session Key: Key length and encryption algorithm.
StartTime: Local computer time that the ticket was requested.
EndTime: Time the ticket becomes no longer valid. When a ticket is past this time, it can no longer be used to authenticate to a service.
RenewUntil: Deadline for ticket renewal.
TimeSkew: Time difference with the Key Distribution Center (KDC).
EncodedTicket: Encoded ticket.

Other options will display the LogonID: Identified in hex

Examples

Query the Kerberos ticket cache to determine if any tickets are missing, if the target server or account is in error, or if the encryption type is not supported due to an Event ID 27 error:

C:\> klist

Query only local System Tickets:

C:\> klist –li 0x3e7

To learn about the specifics of each ticket-granting-ticket that is cached on the computer for a logon session:

C:\> klist tgt

Purge the Kerberos ticket cache, log off, and then log back on:

C:\> klist purge

Purge only local System Tickets:

C:\> klist purge –li 0x3e7

Diagnose a logon session and to locate a logonID for a user or a service:

C:\> klist sessions

Diagnose Kerberos constrained delegation failure, and to find the last error that was encountered:

C:\> klist kcd_cache

Diagnose if a user or a service can get a ticket to a server, or to request a ticket for a specific SPN:

C:\> klist get host/%computername%

To diagnose replication issues across domain controllers, you typically need the client computer to target a specific domain controller. To target the client computer to the specific domain controller:

C:\> klist add_bind CONTOSO KDC.CONTOSO.COM
C:\> klist add_bind CONTOSO.COM KDC.CONTOSO.COM

Query which domain controllers were recently contacted by this computer:

C:\> klist query_bind

Rediscover domain controllers, or to flush the cache before creating new domain controller bindings with klist add_bind:

C:\> klist purge_bind
