k5srvutil - host key table (keytab) manipulation utility
k5srvutil operation [ -i ] [ -f filename ]
k5srvutil allows a system manager to list or change keys currently in
his keytab or to add new keys to the keytab.
Operation must be one of the following:
list lists the keys in a keytab showing version number and
change changes all the keys in the keytab to new randomly-generated
keys, updating the keys in the Kerberos server’s database to
match by using the kadmin protocol. If a key’s version
number doesn’t match the version number stored in the
Kerberos server’s database, then the operation will fail.
The old keys are retained so that existing tickets continue
to work. If the -i flag is given, k5srvutil will prompt for
yes or no before changing each key. If the -k option is
used, the old and new keys will be displayed.
delold Deletes keys that are not the most recent version from the
keytab. This operation should be used some time after a
change operation to remove old keys. If the -i flag is
used, then the program prompts the user whether the old keys
associated with each principal should be removed.
delete deletes particular keys in the keytab, interactively
prompting for each key.
In all cases, the default file used is /etc/krb5.keytab file
unless this is overridden by the -f option.
k5srvutil uses the kadmin program to edit the keytab in place.
However, old keys are retained, so they are available in case of
