4771(F): Kerberos pre-authentication failed.

Applies to

  • Windows 10
  • Windows Server 2020

Event Description:

This event generates every time the Key Distribution Center fails to issue a Kerberos Ticket Granting Ticket (TGT). This can occur when a domain controller doesn’t have a certificate installed for smart card authentication (for example, with a “Domain Controller” or “Domain Controller Authentication” template), the user’s password has expired, or the wrong password was provided.

This event generates only on domain controllers.

This event is not generated if “Do not require Kerberos preauthentication” option is set for the account.

NoteВ В For recommendations, see Security Monitoring Recommendations for this event.

Event XML:

Required Server Roles: Active Directory domain controller.

Minimum OS Version: Windows Server 2008.

Event Versions: 0.

Field Descriptions:

Account Information:

Security ID [Type = SID]: SID of account object for which (TGT) ticket was requested. Event Viewer automatically tries to resolve SIDs and show the account name. If the SID cannot be resolved, you will see the source data in the event.

For example: CONTOSO\dadmin or CONTOSO\WIN81$.

NoteВ В A security identifier (SID) is a unique value of variable length used to identify a trustee (security principal). Each account has a unique SID that is issued by an authority, such as an Active Directory domain controller, and stored in a security database. Each time a user logs on, the system retrieves the SID for that user from the database and places it in the access token for that user. The system uses the SID in the access token to identify the user in all subsequent interactions with Windows security. When a SID has been used as the unique identifier for a user or group, it cannot ever be used again to identify another user or group. For more information about SIDs, see Security identifiers.

Account Name: [Type = UnicodeString]: the name of account, for which (TGT) ticket was requested. Computer account name ends with $ character.

User account example: dadmin

Computer account example: WIN81$

Service Information:

Service Name [Type = UnicodeString]: the name of the service in the Kerberos Realm to which TGT request was sent. Typically has one of the following formats:

krbtgt/DOMAIN_NETBIOS_NAME. Example: krbtgt/CONTOSO

krbtgt/DOMAIN_FULL_NAME. Example: krbtgt/CONTOSO.LOCAL

Network Information:

Client Address [Type = UnicodeString]: IP address of the computer from which the TGT request was received. Formats vary, and include the following:

IPv6 or IPv4 address.

::ffff:IPv4_address.

::1 – localhost.

Client Port [Type = UnicodeString]: source port number of client network connection (TGT request connection).

Additional Information:

Ticket Options: [Type = HexInt32]: this is a set of different Ticket Flags in hexadecimal format.

Ticket Options: 0x40810010

Binary view: 01000000100000010000000000010000

Using MSB 0 bit numbering we have bit 1, 8, 15 and 27 set = Forwardable, Renewable, Canonicalize, Renewable-ok.

Note  In the table below “MSB 0” bit numbering is used, because RFC documents use this style. In “MSB 0” style bit numbering begins from left.

The most common values:

0x40810010 – Forwardable, Renewable, Canonicalize, Renewable-ok

0x40810000 – Forwardable, Renewable, Canonicalize

0x60810010 – Forwardable, Forwarded, Renewable, Canonicalize, Renewable-ok

Bit Flag Name Description
0 Reserved
1 Forwardable (TGT only). Tells the ticket-granting service that it can issue a new TGT—based on the presented TGT—with a different network address based on the presented TGT.
2 Forwarded Indicates either that a TGT has been forwarded or that a ticket was issued from a forwarded TGT.
3 Proxiable (TGT only). Tells the ticket-granting service that it can issue tickets with a network address that differs from the one in the TGT.
4 Proxy Indicates that the network address in the ticket is different from the one in the TGT used to obtain the ticket.
5 Allow-postdate Postdated tickets SHOULD NOT be supported in KILE (Microsoft Kerberos Protocol Extension).
6 Postdated Postdated tickets SHOULD NOT be supported in KILE (Microsoft Kerberos Protocol Extension).
7 Invalid This flag indicates that a ticket is invalid, and it must be validated by the KDC before use. Application servers must reject tickets which have this flag set.
8 Renewable Used in combination with the End Time and Renew Till fields to cause tickets with long life spans to be renewed at the KDC periodically.
9 Initial Indicates that a ticket was issued using the authentication service (AS) exchange and not issued based on a TGT.
10 Pre-authent Indicates that the client was authenticated by the KDC before a ticket was issued. This flag usually indicates the presence of an authenticator in the ticket. It can also flag the presence of credentials taken from a smart card logon.
11 Opt-hardware-auth This flag was originally intended to indicate that hardware-supported authentication was used during pre-authentication. This flag is no longer recommended in the Kerberos V5 protocol. KDCs MUST NOT issue a ticket with this flag set. KDCs SHOULD NOT preserve this flag if it is set by another KDC.
12 Transited-policy-checked KILE MUST NOT check for transited domains on servers or a KDC. Application servers MUST ignore the TRANSITED-POLICY-CHECKED flag.
13 Ok-as-delegate The KDC MUST set the OK-AS-DELEGATE flag if the service account is trusted for delegation.
14 Request-anonymous KILE not use this flag.
15 Name-canonicalize In order to request referrals the Kerberos client MUST explicitly request the «canonicalize» KDC option for the AS-REQ or TGS-REQ.
16-25 Unused
26 Disable-transited-check By default the KDC will check the transited field of a TGT against the policy of the local realm before it will issue derivative tickets based on the TGT. If this flag is set in the request, checking of the transited field is disabled. Tickets issued without the performance of this check will be noted by the reset (0) value of the TRANSITED-POLICY-CHECKED flag, indicating to the application server that the transited field must be checked locally. KDCs are encouraged but not required to honor
the DISABLE-TRANSITED-CHECK option.
Should not be in use, because Transited-policy-checked flag is not supported by KILE.
27 Renewable-ok The RENEWABLE-OK option indicates that a renewable ticket will be acceptable if a ticket with the requested life cannot otherwise be provided, in which case a renewable ticket may be issued with a renew-till equal to the requested end time. The value of the renew-till field may still be limited by local limits, or limits selected by the individual principal or server.
28 Enc-tkt-in-skey No information.
29 Unused
30 Renew The RENEW option indicates that the present request is for a renewal. The ticket provided is encrypted in the secret key for the server on which it is valid. This option will only be honored if the ticket to be renewed has its RENEWABLE flag set and if the time in its renew-till field has not passed. The ticket to be renewed is passed in the padata field as part of the authentication header.
31 Validate This option is used only by the ticket-granting service. The VALIDATE option indicates that the request is to validate a postdated ticket. Should not be in use, because postdated tickets are not supported by KILE.
  • Failure Code [Type = HexInt32]: hexadecimal failure code of failed TGT issue operation. The table below contains the list of the most common error codes for this event:
Code Code Name Description Possible causes
0x10 KDC_ERR_PADATA_TYPE_NOSUPP KDC has no support for PADATA type (pre-authentication data) Smart card logon is being attempted and the proper certificate cannot be located. This can happen because the wrong certification authority (CA) is being queried or the proper CA cannot be contacted in order to get Domain Controller or Domain Controller Authentication certificates for the domain controller.
It can also happen when a domain controller doesn’t have a certificate installed for smart cards (Domain Controller or Domain Controller Authentication templates).
0x17 KDC_ERR_KEY_EXPIRED Password has expired—change password to reset The user’s password has expired.
0x18 KDC_ERR_PREAUTH_FAILED Pre-authentication information was invalid The wrong password was provided.
  • Pre-Authentication Type [Type = UnicodeString]: the code of pre-Authentication type which was used in TGT request.

## Table 5. Kerberos Pre-Authentication types.

Type Type Name Description
0 Logon without Pre-Authentication.
2 PA-ENC-TIMESTAMP This is a normal type for standard password authentication.
11 PA-ETYPE-INFO The ETYPE-INFO pre-authentication type is sent by the KDC in a KRB-ERROR indicating a requirement for additional pre-authentication. It is usually used to notify a client of which key to use for the encryption of an encrypted timestamp for the purposes of sending a PA-ENC-TIMESTAMP pre-authentication value.
Never saw this Pre-Authentication Type in Microsoft Active Directory environment.
15 PA-PK-AS-REP_OLD Used for Smart Card logon authentication.
16 PA-PK-AS-REQ Request sent to KDC in Smart Card authentication scenarios.
17 PA-PK-AS-REP This type should also be used for Smart Card authentication, but in certain Active Directory environments, it is never seen.
19 PA-ETYPE-INFO2 The ETYPE-INFO2 pre-authentication type is sent by the KDC in a KRB-ERROR indicating a requirement for additional pre-authentication. It is usually used to notify a client of which key to use for the encryption of an encrypted timestamp for the purposes of sending a PA-ENC-TIMESTAMP pre-authentication value.
Never saw this Pre-Authentication Type in Microsoft Active Directory environment.
20 PA-SVR-REFERRAL-INFO Used in KDC Referrals tickets.
138 PA-ENCRYPTED-CHALLENGE Logon using Kerberos Armoring (FAST). Supported starting from Windows Server 2020 domain controllers and Windows 8 clients.
This type shows in Audit Failure events.

Certificate Information:

Certificate Issuer Name [Type = UnicodeString]: the name of Certification Authority which issued smart card certificate. Populated in Issued by field in certificate. Always empty for 4771 events.

Certificate Serial Number [Type = UnicodeString]: smart card certificate’s serial number. Can be found in Serial number field in the certificate. Always empty for 4771 events.

Certificate Thumbprint [Type = UnicodeString]: smart card certificate’s thumbprint. Can be found in Thumbprint field in the certificate. Always empty for 4771 events.

Security Monitoring Recommendations

For 4771(F): Kerberos pre-authentication failed.

Type of monitoring required Recommendation
High-value accounts: You might have high-value domain or local accounts for which you need to monitor each action.
Examples of high-value accounts are database administrators, built-in local administrator account, domain administrators, service accounts, domain controller accounts and so on.
Monitor this event with the “Security ID” that corresponds to the high-value account or accounts.
Anomalies or malicious actions: You might have specific requirements for detecting anomalies or monitoring potential malicious actions. For example, you might need to monitor for use of an account outside of working hours. When you monitor for anomalies or malicious actions, use the “Security ID” (with other information) to monitor how or when a particular account is being used.
Non-active accounts: You might have non-active, disabled, or guest accounts, or other accounts that should never be used. Monitor this event with the “Security ID” that corresponds to the accounts that should never be used.
Account whitelist: You might have a specific whitelist of accounts that are the only ones allowed to perform actions corresponding to particular events. If this event corresponds to a “whitelist-only” action, review the “Security ID” for accounts that are outside the whitelist.
Account naming conventions: Your organization might have specific naming conventions for account names. Monitor “Subject\Account Name” for names that don’t comply with naming conventions.

You can track all 4771 events where the Client Address is not from your internal IP range or not from private IP ranges.

If you know that Account Name should be used only from known list of IP addresses, track all Client Address values for this Account Name in 4771 events. If Client Address is not from the whitelist, generate the alert.

All Client Address = ::1 means local authentication. If you know the list of accounts which should log on to the domain controllers, then you need to monitor for all possible violations, where Client Address = ::1 and Account Name is not allowed to log on to any domain controller.

All 4771 events with Client Port field value > 0 and –>

Synonyms & Antonyms for binary

Did You Know?

The animals went in two by two, the elephant and the kangaroo. . .. It was a binary parade of sorts that went into Noah’s ark «for to get out of the rain» – the critters were represented in pairs. If you recall those partnered beasts, you’ll remember the etymology of binary, because it traces to the Latin bini, which translates as «two by two.» Although «binary» can be used for anything with two parts, it is now used especially in relation to computers and information processing. Digital computers use the binary number system, which includes only the digits 0 and 1, to process even complex data. In binary form, for instance, the word HELLO looks like this: 1001000 1000101 1001100 1001100 1001111.
