How can "NP" be set in /etc/shadow?
I'm looking for an "official" way to set a users password-entry in /etc/shadow from any possible entry like "*LK*" or "", or even from an encrypted one to "NP".
I know that the file could be edited manually, and I know that it could be solved with the "sed" command. The first possibility (manually) isn't possible because everything has to be done by adding a package. The second possibility won't be accepted because of security reasons: if the shadow-file would be damaged, the access to the whole system could be lost.
After crawling through nearly all man-pages I gave up my "research". Is there anybody out there who can help me?
