Ktutil - Kerberos keytab file maintenance utility SYNOPSIS. Ktutil DESCRIPTION. The ktutil command invokes a command interface from which an administrator can read, write, or edit entries in a keytab or Kerberos V4 srvtab file. The create-keytab script, when executed will ask a number of questions to guide the creation of the keytab. At the end the keytab will be validated to ensure it was created successfully. There are a number of features but of note is the ability to create a keytab against an existing service account and reset the password to something secret. Generate the keytab file. Use the ktpass on the command line utility to export the keytab file. By running the following ktpass command, you generate a keytab file and create a mapping that associates the Kerberos service name with the identity in Active Directory.

NAME
kinit - obtain and cache Kerberos ticket-granting ticketSYNOPSIS
kinit[-V][-llifetime][-sstart_time][-rrenewable_life][-p | -P][-f | -F][-a][-A][-C][-E][-v][-R][-k [-tkeytab_file]][-ccache_name][-n][-Sservice_name][-Iinput_ccache][-Tarmor_ccache][-Xattribute[=value]][principal]
DESCRIPTION
kinit obtains and caches an initial ticket-granting ticket forprincipal. If principal is absent, kinit chooses an appropriateprincipal name based on existing credential cache contents or thelocal username of the user invoking kinit. Some options modify thechoice of principal name.
OPTIONS
For example, kinit -l 5:30 or kinit -l 5h30m.
If the -l option is not specified, the default ticket lifetime(configured by each site) is used. Specifying a ticket lifetimelonger than the maximum ticket lifetime (configured by each site)will not override the configured maximum ticket lifetime.
start_time specifies the duration of the delay before the ticketcan become valid.
Keytab File Location
Note that renewable tickets that have expired as reported byklist(1) may sometimes be renewed using this option,because the KDC applies a grace period to account for client-KDCclock skew. See krb5.conf(5)clockskew setting.
For fully anonymous Kerberos, configure pkinit on the KDC andconfigure pkinit_anchors in the client's krb5.conf(5).Then use the -n option with a principal of the form @REALM(an empty principal name followed by the at-sign and a realmname). If permitted by the KDC, an anonymous ticket will bereturned.

A second form of anonymous tickets is supported; theserealm-exposed tickets hide the identity of the client but not theclient's realm. For this mode, use kinit -n with a normalprincipal name. If supported by the KDC, the principal (but notrealm) will be replaced by the anonymous principal.
As of release 1.8, the MIT Kerberos KDC only supports fullyanonymous operation.
-Iinput_ccacheSpecifies the name of a credentials cache that already contains aticket. When obtaining that ticket, if information about how thatticket was obtained was also stored to the cache, that informationwill be used to affect how new credentials are obtained, includingpreselecting the same methods of authenticating to the KDC. Garden of shadows sims.
The default cache location may vary between systems. If theKRB5CCNAME environment variable is set, its value is used tolocate the default cache. If a principal name is specified andthe type of the default cache supports a collection (such as theDIR type), an existing cache containing credentials for theprincipal is selected or a new one is created and becomes the newprimary cache. Otherwise, any existing contents of the defaultcache are destroyed by kinit.
The following attributes are recognized by the PKINITpre-authentication mechanism:
ENVIRONMENT
kinit uses the following environment variables:
- FILE:/tmp/krb5cc_%{uid}
- default location of Kerberos 5 credentials cache
- FILE:/etc/krb5.keytab
- default location for the local host's keytab.

Active directory requires Kerberos service principal names to be mapped to a user account before a keytab can be generated.
You can add SPN names to a user with samba-tool, this is provided with your samba 4 installation.
This should return without error.
Once the SPN is added, you can then generate a keytab for the user with samba-tool, by running the following: X arcade config file for mame.
This should then produce a keytab called <name>.keytab containing the users upn or the spn, depending on which is given with '--principal' and this can then be copied to your target machine or service.
Note: replace <sAMAccount name> with a valid user name, <SPN> with the spn you added earlier and <name> with whatever you what the keytab to be called, this can also include a path to where you want the keytab to be created.You should only use <sAMAccount name> or <SPN>, you should not use both.
By default a users keytab will contain the following enctypes:
But if you export a keytab using '--principal' it will only contain these enctypes:
To add the two stronger enctypes: Kcpm utility pro 5.1 for macos.
Log into A DC as root, then run 'kinit Administrator'. You can then use the 'net ads enctypes set' command to add the enctypes
This should print something like this:
