NAME

       ipa-rmkeytab - Remove a kerberos principal from a keytab

SYNOPSIS

       ipa-rmkeytab [ -p principal-name ] [ -k keytab-file ] [ -r realm ] [ -d ]

DESCRIPTION

       Removes a kerberos principal from a keytab.

       Kerberos keytabs are used for services (like sshd) to perform kerberos authentication. A keytab is a file
       with one or more secrets (or keys) for a kerberos principal.

       A  kerberos  service  principal  is  a  kerberos  identity  that  can be used for authentication. Service
       principals contain the name of the service, the hostname of the server, and the realm name.

       ipa-rmkeytab provides two ways to remove  principals.   A  specific  principal  can  be  removed  or  all
       principals for a given realm can be removed.

       All encryption types and versions of a principal are removed.

       The realm may be included when removing a specific principal but it is not required.

       NOTE:  removing  a  principal  from  the  keytab does not affect the Kerberos principal stored in the IPA
       server. It merely removes the entry from the local keytab.

OPTIONS

       -p principal-name
              The non-realm part of the full principal name.

       -k keytab-file
              The keytab file to remove the principal(s) from.

       -r realm
              A realm to remove all principals for.

       -d     Debug mode. Additional information is displayed.

EXAMPLES

       Remove the NFS service principal on the host foo.example.com from /tmp/nfs.keytab.

          # ipa-rmkeytab -p nfs/foo.example.com -k /tmp/nfs.keytab

       Remove the ldap service principal on the host foo.example.com from /etc/krb5.keytab.

          # ipa-rmkeytab -p ldap/foo.example.com -k /etc/krb5.keytab
