See line 32 in this same article.

| 0x14 | KDC\_ERR\_TGT\_REVOKED | TGT has been revoked | Since the remote KDC may change its PKCROSS key while there are PKCROSS tickets still active, it SHOULD cache the old PKCROSS keys until the last issued PKCROSS ticket expires. Otherwise, the remote KDC will respond to a client with a KRB-ERROR message of type KDC\_ERR\_TGT\_REVOKED. See [RFC1510](https://www.ietf.org/proceedings/49/I-D/draft-ietf-cat-kerberos-pk-cross-07.txt) for more details. |
| 0x15 | KDC\_ERR\_CLIENT\_NOTYET | Client not yet valid—try again later | No information. |
| 0x16 | KDC\_ERR\_SERVICE\_NOTYET | Server not yet valid—try again later | No information. |
| 0x17 | KDC\_ERR\_KEY\_EXPIRED | Password has expired—change password to reset | The user’s password has expired.<br>This error code cannot occur in event “[4768](event-4768.md). A Kerberos authentication ticket (TGT) was requested”. It occurs in “[4771](event-4771.md). Kerberos pre-authentication failed” event. |
| 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.<br>This error code cannot occur in event “[4768](event-4768.md). A Kerberos authentication ticket (TGT) was requested”. It occurs in “[4771](event-4771.md). Kerberos pre-authentication failed” event. |
| 0x19 | KDC\_ERR\_PREAUTH\_REQUIRED | Additional pre-authentication required | This error often occurs in UNIX interoperability scenarios. MIT-Kerberos clients do not request pre-authentication when they send a KRB\_AS\_REQ message. If pre-authentication is required (the default), Windows systems will send this error. Most MIT-Kerberos clients will respond to this error by giving the pre-authentication, in which case the error can be ignored, but some clients might not respond in this way. |
| 0x1A | KDC\_ERR\_SERVER\_NOMATCH | KDC does not know about the requested server | No information. |
