Dear all,

How to deny a normal user , for changing his own password.

Thanks

Maybe something like:

Code:

chmod -s `which passwd`

I don't know if you should do that.. nor why you'd want to do that.

Not sure if this will work, but you can also use the chage command set the MINIMUM days for a password change to something like 9999. This will force a user to wait 9999 days before he or she can change their password

Another thing to look at would be in /etc/pam.d/. Maybe there is a setting somewhere in there to do this by default.

I'd go for chmod o-rx `which passwd` myself.

same effect, except that passwd still works. You could go further and enable specific users or groups to execute the passwd command using posix acl's...
