7 .TH KPASSWD 1 "Kerberos Version 4.0" "MIT Project Athena"
10 kpasswd \- change a user's Kerberos password
26 .IR username[.instance][@realm] ]
30 command is used to change a Kerberos principal's password.
34 option is specified, a brief summary of the options is printed, and
42 is used as the principal name rather than the username of the user
45 (This is determined from the ticket file if it exists;
46 otherwise, it is determined from the unix user id.)
52 is used as the instance rather than a null instance.
58 is used as the realm rather than the local realm.
62 option is specified, a fully qualified kerberos
63 principal can be given.
66 The utility prompts for the current Kerberos password (printing
67 the name of the principal for which it intends to change the password),
68 which is verified by the Kerberos server. If the old password is
69 correct, the user is prompted twice for the new password. A message is
70 printed indicating the success or failure of the password changing
76 does not handle names, instances, or realms with special
77 characters in them when the -n, -i, or -r options are used. Any
78 valid fullname is accepted, however, if the -u option is used.
80 If the principal whose password you are trying to change does
81 not exist, you will not be told until after you have entered the
85 kerberos(1), kinit(1), passwd(1), kadmin(8)
