/*
 * resetpwtime.c: Reset a user's password change time on HP-UX.
 *
 * Author: Darren Tucker (dtucker at zip.com.au), 2003-11-18.
 * Hereby placed in the public domain.
 *
 * Compile with: cc -o resetpwtime resetpwtime.c -lsec
 *
 * Requires root privilege, making this setuid is *NOT* recommended.
 *
 * Why?  I do automated testing in both normal and Trusted Mode on a single
 * box, by converting with /usr/lbin/tsconvert.  Unfortunately, every time
 * this happens, it resets the password change time and requires it to be
 * changed at next login.  This messes up my tests, so I wrote this quick
 * hack to rest the password change time for a single account, which runs
 * from my test script.
