Nis maps not updating

Rated 4.58/5 based on 527 customer reviews

On any other result, rpc.yppasswdd will report failure to the client.

Note that the program specified by the -x option is responsible for doing any NIS make and build, and for doing any necessary validation on the shell and gcos field information supplied.

rpc.yppasswdd will search the system's passwd file for the specified user name, verify that the given (old) password matches, and update the entry.

If the user specified does not exist, or if the password, UID or GID doesn't match the information in the password file, the update request is rejected, and an error returned to the client.

Instead of rpc.yppasswdd editing the passwd & shadow files, the specified program will be run to do the editing.

There is a defined protocol used to communicate with this external program, which has total freedom in how it propagates the change request. Using Shadow passwords alongside NIS does not make too much sense, because the supposedly inaccesible passwords now become readable through a simple invocation of ypcat(1).If this version of the server is compiled with the CHECKROOT=1 option, the password given is also checked against the systems root password.After updating the passwd file and returning a success notification to the client, rpc.yppasswdd executes the pwupdate script that updates the NIS server's passwd.* and shadow.byname maps.Welcome to Linux, a friendly and active Linux Community.
