If the user has done a \fBkeylogin\fR(1), and a publickey/secretkey pair exists for the user in the \fBNIS\fR \fBpublickey.byname\fR map, \fByppasswd\fR also re-encrypts the secretkey with the new password. The \fBNIS\fR password may be different from the local one if the account also appears in the \fBpasswd\fR(5) file on the machine. .sp .LP \fByppasswd\fR executes \fBpasswd -r nis\fR. Restrictions on the password and who may change it are documented in the \fBpasswd\fR(1) manual page. .sp .LP The \fBNIS\fR password daemon, \fBrpc.yppasswdd\fR must be running on your \fBNIS\fR server in order for the new password to take effect. .SH ATTRIBUTES .sp .LP See \fBattributes\fR(7) for descriptions of the following attributes: .sp .TS tab( ) box; cw(2.75i) |cw(2.75i) lw(2.75i) |lw(2.75i) . ATTRIBUTE TYPE ATTRIBUTE VALUE _ Availability system/network/nis _ Interface Stability Obsolete .TE .sp .SH SEE ALSO .sp .LP \fBkeylogin\fR(1), \fBlogin\fR(1), \fBpasswd\fR(1), \fBgetpwnam\fR(3C), \fBgetspnam\fR(3C), \fBsecure_rpc\fR(3C), \fBnsswitch.conf\fR(5), \fBattributes\fR(7) .SH WARNINGS .sp .LP Even after the user has successfully changed their password using this command, the subsequent \fBlogin\fR(1) using the new password will be successful only if the user's password and shadow information is obtained from NIS. See \fBgetpwnam\fR(3C), \fBgetspnam\fR(3C), and \fBnsswitch.conf\fR(5). .SH NOTES .sp .LP The use of \fByppasswd\fR is discouraged, as it is now only a wrapper around the \fBpasswd\fR(1) command, which should be used instead. Using \fBpasswd\fR(1) with the \fB-r\fR \fBnis\fR option will achieve the same results, and will be consistent across all the different name services available. .SH BUGS .sp .LP The update protocol passes all the information to the server in one \fBRPC\fR call, without ever looking at it. Thus, if you type your old password incorrectly, you will not be notified until after you have entered your new password.
