- .SH SYNOPSIS
- .sp
- \fBkpasswd\fP [\fIprincipal\fP]
- .SH DESCRIPTION
- .sp
- The kpasswd command is used to change a Kerberos principal\(aqs password.
- kpasswd first prompts for the current Kerberos password, then prompts
- the user twice for the new password, and the password is changed.
- .sp
- If the principal is governed by a policy that specifies the length
- and/or number of character classes required in the new password, the
- new password must conform to the policy. (The five character classes
- are lower case, upper case, numbers, punctuation, and all other
- characters.)
- .SH OPTIONS
- .INDENT 0.0
- .TP
- .B \fIprincipal\fP
- Change the password for the Kerberos principal principal.
- Otherwise, kpasswd uses the principal name from an existing ccache
- if there is one; if not, the principal is derived from the
- identity of the user invoking the kpasswd command.
