Unfortunately the answer is that keytabs for Kerberos cannot be generated on Windows 7. It must be generated using the ktpass utility on a Windows Server OS. The Keytab must be generated on either a member server or a domain controller of the Active Directory domain using the ktpass.exe command. Use the Windows Server built-in utility ktpass.exe to create the keytab. Kerberos keytab tool has stopped working - Windows can check online for a solution to the problem.
This method of creating a keytab file uses the ktpass.exe command that is included with Microsoft Support Tools.
- On a computer with the Microsoft Support Tools installed (it is not necessary to be logged in as a privileged user), execute the following command, replacing the <database account name>, <REALM>, <crypto algorithm> and <database account password> with the appropriate values. <crypto algorithm> can be one of , aes128-sha1, aes256-sha1 or rc4-hmac-nt. Make sure that the selected crypto algorithm is also specified in the krb5.conf file. Note: It is not critical to use the name 'spotfire‐database.keytab' for the keytab file, but the following instructions assume that this name is used.Example of creating a keytab file for the Spotfire database account named 'spotuser' in the research.example.com domain:
- Copy the spotfire-database.keytab file to the directory <installation dir>jdkjrelibsecurity (Windows) or <installation dir>/jdk/jre/lib/security (Unix) in Spotfire Server. Note: Because this file contains sensitive information, it must be handled with care. The file must not under any circumstances be readable by unauthorized users.Note: If you change the password of the Kerberos service account, you must re-create the keytab file.
