Comment 21 for bug 270781

At the time the unix_chkpwd starts crashing in the screensaver can you try it to run manually:

echo -ne '<password>\0000' | /sbin/unix_chkpwd <user> nullok ; echo $?

Replace the <password> with the password of your account and the <user> with the user name.

Does it crash too? If it does, can you find any related entries in the audit log - use ausearch -x unix_chkpwd.

Does it still crash if you replace nullok with some bogus word? It should return 4 as exit value and add an audit entry and of course not crash.
