To delete a principal, use the kadmin delete_principal command,
which requires the “delete” administrative privilege. The syntax is:
delete_principal [-force] principal
delete_principal has the alias delprinc. The
-force option causes delete_principal not to ask if you're
sure. For example:
kadmin: delprinc jennifer
Are you sure you want to delete the principal
"jennifer@ATHENA.MIT.EDU"? (yes/no): yes
Principal "jennifer@ATHENA.MIT.EDU" deleted.
Make sure that you have removed this principal from
all ACLs before reusing.
