Otherwise, the principal name is derived from the identity -of the user invoking the -.I v5passwd -command. - -.PP -The -.I v5passwd -command prompts for the current Kerberos password, which is verified by the -Kerberos server. If the old password is correct, the user is prompted twice -for the new password. Success or failure is indicated by messages printed -out by -.I v5passwd. - - -.SH FILES -.TP 2i -/tmp/tkt_kpw_[uid] -the temporary credentials cache ([uid] is the decimal UID of the user) for -the lifetime of the password changing operation. -.SH SEE ALSO -kadmin(8), kadmind(8), v5passwdd(8) -.SH BUGS |
