Initial import of KTH eBones. This has been cleaned up to only include
the "core" Kerberos functionality. The rest of the userland will get their
own changes later.

If the +.Fl k +option is used, the old and new keys will be displayed. +.It add +allows the user to add a key. +add +prompts for name, instance, realm, and key version number, asks +for confirmation, and then asks for a password. +.Nm +then converts the password to a key and appends the keyfile with the +new information. If the +.Fl k +option is used, the key is displayed. +.It get +gets a service from the Kerberos server, possibly creating the +principal. Names, instances and realms for the service keys to get are +prompted for. The default principal used in the kadmin transcation is +your root instance. This can be changed with the +.Fl p +option. +.El +.Pp +In all cases, the default file used is KEY_FILE as defined in krb.h +unless this is overridden by the +.Fl f +option. +.Pp +A good use for +.Nm +would be for adding keys to a keyfile. A system manager could +ask a kerberos administrator to create a new service key with +.Xr kadmin 8 +and could supply an initial password. Then, he could use +.Nm +to add the key to the keyfile and then to change the key so that it +will be random and unknown to either the system manager or the +kerberos administrator. + +.Nm +always makes a backup copy of the keyfile before making any changes. + +.Sh DIAGNOSTICS +If +.Nm +should exit on an error condition at any time during a change or add, +a copy of the original keyfile can be found in +.Pa filename Ns .old +where +.Pa filename +is the name of the keyfile, and a copy of the file with all new +keys changed or added so far can be found in +.Pa filename Ns .work. +The original keyfile is left unmodified until the program exits at +which point it is removed and replaced it with the workfile. +Appending the workfile to the backup copy and replacing the keyfile +with the result should always give a usable keyfile, although the +resulting keyfile will have some out of date keys in it. + +.Sh SEE ALSO +.Xr kadmin 8 , +.Xr ksrvtgt 1 + +.Sh AUTHOR +Emanuel Jay Berkenbilt, MIT Project Athena |
