Oct 16, 2017 Parameter Description /out: Specifies the name of the Kerberos version 5.keytab file to generate. Note: This is the.keytab file you transfer to a computer that isn't running the Windows operating system, and then replace or merge with your existing.keytab file, /Etc/Krb5.keytab. /princ: Specifies the principal name in the form. Mar 10, 2014 Instead you will have to log into a Linux system and create the keytab there and then securely transport the file back to your Macintosh where it will be stored as the file /etc/krb5.keytab (you can use the SSH file copy utility scp to accomplish this). On the Linux system, run this command. Jun 11, 2020 Creating a Kerberos service principal name and keytab file using z/OS KDC: Before Simple and Protected GSS-API Negotiation (SPNEGO) web authentication and Kerberos authentication can be used, the WebSphere Application Server administrator must first create a Kerberos keytab file on the host that is running WebSphere Application Server.

Applies to: Windows Server (Semi-Annual Channel), Windows Server 2019, Windows Server 2016, Windows Server 2012 R2, Windows Server 2012
Configures the server principal name for the host or service in Active Directory Domain Services (AD DS) and generates a .keytab file that contains the shared secret key of the service. The .keytab file is based on the Massachusetts Institute of Technology (MIT) implementation of the Kerberos authentication protocol. Cabaret voltaire voice of america blogspot. The ktpass command-line tool allows non-Windows services that support Kerberos authentication to use the interoperability features provided by the Kerberos Key Distribution Center (KDC) service.
Syntax
Parameters
Parameter | Description |
---|---|
/out <filename> | Specifies the name of the Kerberos version 5 .keytab file to generate. Note: This is the .keytab file you transfer to a computer that isn't running the Windows operating system, and then replace or merge with your existing .keytab file, /Etc/Krb5.keytab. |
/princ <principalname> | Specifies the principal name in the form host/[email protected]. Warning: This parameter is case-sensitive. |
/mapuser <useraccount> | Maps the name of the Kerberos principal, which is specified by the princ parameter, to the specified domain account. |
/mapop {add|set} | Specifies how the mapping attribute is set.
|
{-|+} desonly | DES-only encryption is set by default.
|
/in <filename> | Specifies the .keytab file to read from a host computer that is not running the Windows operating system. |
/pass {password|*|{-|+}rndpass} | Specifies a password for the principal user name that is specified by the princ parameter. Use * to prompt for a password. |
/minpass | Sets the minimum length of the random password to 15 characters. |
/maxpass | Sets the maximum length of the random password to 256 characters. |
/crypto {DES-CBC-CRC|DES-CBC-MD5|RC4-HMAC-NT|AES256-SHA1|AES128-SHA1|All} | Specifies the keys that are generated in the keytab file:
Note: Because the default settings are based on older MIT versions, you should always use the /crypto parameter. |
/itercount | Specifies the iteration count that is used for AES encryption. The default ignores itercount for non-AES encryption and sets AES encryption to 4,096. |
/ptype {KRB5_NT_PRINCIPAL|KRB5_NT_SRV_INST|KRB5_NT_SRV_HST} | Specifies the principal type.
|
/kvno <keyversionnum> | Specifies the key version number. The default value is 1. |
/answer {-|+} | Sets the background answer mode:
|
/target | Sets which domain controller to use. The default is for the domain controller to be detected, based on the principal name. If the domain controller name doesn't resolve, a dialog box will prompt for a valid domain controller. |
/rawsalt | forces ktpass to use the rawsalt algorithm when generating the key. This parameter is optional. |
{-|+}dumpsalt | The output of this parameter shows the MIT salt algorithm that is being used to generate the key. |
{-|+}setupn | Sets the user principal name (UPN) in addition to the service principal name (SPN). The default is to set both in the .keytab file. |
{-|+}setpass <password> | Sets the user's password when supplied. If rndpass is used, a random password is generated instead. |
/? | Displays Help for this command. |
Remarks
- Services running on systems that aren't running the Windows operating system can be configured with service instance accounts in AD DS. This allows any Kerberos client to authenticate to services that are not running the Windows operating system by using Windows KDCs.
- The /princ parameter isn't evaluated by ktpass and is used as provided. There's no check to see if the parameter matches the exact case of the userPrincipalName attribute value when generating the Keytab file. Case-sensitive Kerberos distributions using this Keytab file might have problems if there's no exact case match, and could even fail during pre-authentication. To check and retrieve the correct userPrincipalName attribute value from a LDifDE export file. For example:

To create a Kerberos .keytab file for a host computer that isn't running the Windows operating system, you must map the principal to the account and set the host principal password.
- Rogers powertone snare serial numbers. Use the active directory User and computers snap-in to create a user account for a service on a computer that is not running the Windows operating system. For example, create an account with the name User1.
- Use the ktpass command to set up an identity mapping for the user account by typing:Airtel bill pdf download. NoteYou cannot map multiple service instances to the same user account. Chroma configurator mac download.
- Merge the .keytab file with the /Etc/Krb5.keytab file on a host computer that isn't running the Windows operating system.
