That is, the first component of the SPN will always be the user supplied name as in the following example:. To resolve this issue on a file server that is running the SMB version 1 protocol, add the DisableStrictNameChecking value to the registry:. We don't recommend that you resolve this issue for a file server that isn't Windows-based by typing the following commands in an elevated Command Prompt window on a Windows-based computer.
You would have to be logged on with Domain Administrator credentials. To stop the network trace in an unsuccessful scenario, type the following command, and then press Enter:. To collect registry settings on the file server, select Start , select Run , type the command in the Open box, and then select OK. As we were not able to deploy it at that time, we ended up shutting it down for the duration. We just turned it back on and are having issues getting replication to work.
I personally suspect the main issue is DNS related but I cant be sure. I get one of these errors in the log on the suspect DC for each of the other domain controllers there are 6 others on a regular basis:.
The target name used was blahblahblah. This indicates that the target server failed to decrypt the ticket provided by the client. This can occur when the target server principal name SPN is registered on an account other than the account the target service is using.
Please ensure that the target SPN is registered on, and only registered on, the account used by the server. This error can also happen when the target service is using a different password for the target service account than what the Kerberos Key Distribution Center KDC has for the target service account.
A klist at that point should then show that you have retrieved a TGT ticket granting ticket from the AD domain controller.
If this fails, go back and troubleshoot the Kerberos configuration. This should return a listing of the account information from Active Directory.
If this does not work, users will not be able to login, even if Kerberos is working fine. If you run into errors or failures here, go back and double-check the LDAP configuration. One common source of errors is the name of the LDAP bind account, so be sure that is correct. This will be true as long as you used the ktpass. Because the PAM Kerberos configuration, by default, does not require a client keytab, and does not attempt to validate the tickets granted by the TGT.
This means that as long as the SPN s are mapped to the accounts in AD, the keytab is not necessarily required. Unlike Windows systems, home directories are required on Linux-based systems. As a result, we must provide home directories for each AD user that will log in to a Linux-based system. This topic contains information about Kerberos authentication in Windows Server and Windows 8. The Windows Server operating systems implement the Kerberos version 5 authentication protocol and extensions for public key authentication, transporting authorization data, and delegation.
Initial user authentication is integrated with the Winlogon single sign-on architecture. Active Directory Domain Services is required for default Kerberos implementations within the domain or forest. Services that run on Windows operating systems can impersonate a client computer when accessing resources on the client's behalf. In many cases, a service can complete its work for the client by accessing resources on the local computer.
When a client computer authenticates to the service, NTLM and Kerberos protocol provide the authorization information that a service needs to impersonate the client computer locally.
However, some distributed applications are designed so that a front-end service must use the client computer's identity when it connects to back-end services on other computers. Kerberos authentication supports a delegation mechanism that enables a service to act on behalf of its client when connecting to other services.
