REM This script generates the Service Principal Names (SPNs) and keytab files required for 
REM Kerberos SSO with Apache.
REM This script executes set, setspn, and ktpass commands included in any Windows Server 
REM Operating System from 2003 on.
REM Before running this script you must enter configuration information for the setspn and 
REM ktpass commands. 
REM Elements that require your configuration information are enclosed in as such:
REM  ! -- and --!. 
REM After you customize this file, save it as a .bat file, and run on a domain-joined 
REM computer. 
REM This script must be run by a Domain admin.

REM **********

REM The following set command will prompt the domain admin for credentials of the 
REM Tableau Server service account. 
REM This account must be a valid domain user account.
REM If the password contains a literal \" (blackslash - double quote), all backslashes 
REM immediately before the double quote must be
REM duplicated when typed for the password to work, e.g. if password contains 
REM  \" replace with \\", if passwords contains \\" replace with \\\\"

set /p adpass= "Enter password for the Tableau Server service account."
set adpass=!adpass:"=\"!

REM **********

REM The following setspn commands create the SPN in the domain.
REM More information on setspn can be found here: 
REM http://technet.microsoft.com/en-us/library/cc731241(WS.10).aspx  
REM Enter the canonical FQDN and the host names for Tableau Server followed by the  
REM Tableau Server service account name.
REM Use this syntax: HTTP/hostname domain\service_account_name.
REM The example below shows syntax for a computer named "tableau01" in the "example.lan"  
REM domain, with service account, "tab-serv-account":
REM setspn -s HTTP/tableau01 example\tab-serv-account
REM setspn -s HTTP/tableau01.example.lan example\tab-serv-account  
REM DNS and AD are not case sensitive, but the keytab files are.  Verify that host names  
REM match letter case as stored in DNS. 
REM Use Windows Server's DNS Manager utility to verify host name case.

REM The following commands create the keytab file in the same directory where the 
REM bat file is run. More information on ktpass can be found here: 
REM https://docs.microsoft.com/en-us/windows-server/administration/windows-commands/ktpass 
REM Note: keytab files are case-sensitive.
REM The realm following the FQDN should be all uppercase.
REM Syntax is:
REM ktpass /princ HTTP/!--FQDN--!@!--Kerberos_Realm--! /pass !adpass!
REM /pttype KRB5_NTPRINCIPAL /crypto !--cipher--! /out keytabs\kerberos.keytab
REM Best practice: specify the /crypto value that is required by your KDC. 
REM Options for /crypto = {DES-CBC-CRC|DES-CBC-MD5|AES256-SHA1|AES128-SHA1|All}
REM Do not specify /crypto All because it will result in a keytab that contains ciphers that are not supported
REM and cause errors.
REM When using AES256-SHA1 OR AES128-SHA1, the /mapuser option must be included 
REM in the ktpass command to ensure the keytab file is mapped properly to the user. For example:
REM ktpass /princ HTTP/!--FQDN--!@!--Kerberos_Realm--! /pass !adpass! /ptype KRB5_NT_PRINCIPAL /mapuser <domain\username> /crypto AES256-SHA1 /out keytabs\kerberos.keytab
REM The following example shows the ktpass syntax with the example.lan configuration from above:
REM ktpass /princ HTTP/!--FQDN--!@!--Kerberos_Realm--! /pass !adpass! /ptype KRB5_NT_PRINCIPAL /crypto DES-CBC-CRC /out keytabs\kerberos.keytab
