/usr/bin/ktutil
The ktutil command is an interactive command-line interface utility for managing the keylist in keytab files. You must read in a keytab's keylist before you can manage it. Also, the user running the ktutil command must have read/write permissions on the keytab. For example, if a keytab is owned by root, which it typically is, ktutil must be run as root to have the appropriate permissions.
clear
Clears the current keylist.
rkt file
Reads a keytab into the current keylist. You must specify a keytab file to read.
wkt file
Writes the current keylist to a keytab file. You must specify a keytab file to write. If the keytab file already exists, the current keylist is appended to the existing keytab file.
addent number
Adds an entry to the current keylist. Specify the entry by the keylist slot number.
delent number
Deletes an entry from the current keylist. Specify the entry by the keylist slot number.
l
Lists the current keylist.
lr
Lists available requests (commands).
exit
q
Exits utility.
Example 1 Deleting a principal from a file
The following example deletes the host/denver@ACME.com principal from the /etc/krb5/krb5.keytab file. Notice that if you want to delete an entry from an existing keytab, you must first write the keylist to a temporary keytab and then overwrite the existing keytab with the temporary keytab. This is because the wkt command actually appends the current keylist to an existing keytab, so you can't use it to overwrite a keytab.
