- pwdiff takes multiple password files and compares them in an
- intelligent way. For instance, it will report on different names
- with the same uid, but let pass the same name with the same uid.
-
- I wrote it one day when we had to join two password files from
- different machines.
-
- What happened was that we started out with one shared password file in
- a small LAN environment. Over time, more machines came on-line.
- New administrators sometimes shared the old password file, and
- sometimes just copied it. Gradually it diverged, so that some of the
- uids mapped to multiple users across the LAN.
-
- Eventually our LAN got big enough, so that we hired a sitewide admin,
- and he wanted to use one common password file. This makes NFS access
- much easier, for example. So I wrote this program to solve his
- problem. I figure this very same thing must happen to lots of sites,
- so to save you some grief, here it is. Send bugs, improvements, and
- cash to me.
