- I looked into this problem a few weeks ago. Here is my summary to the

-
- The executive summary:
- You cannot use password aging with NIS under SunOS 4.X.
-
- More details:
-
- If you use NIS under SunOS 4.X, password aging is terribly broken to
- the point where it is essentially useless ! The "passwd -y" or
- "yppasswd" do not work, because (at least) the daemon rpc.yppasswdd is
- broken. Essentially, rpc.yppasswdd in obtaining the encrypted password
- does not strip off the last bytes that pertain to password aging,
- but just bombs out with the error message "Bad password in adjunct".
- Someone said that Sun "do not support passwd aging with NIS and don't
- have plans to in the near future."
- Another statement: "Password aging does not work with NIS, C2 or not.
- Fixed in Solaris 2.0."
-
- FLAME: What's the point of Sun offering password-aging in SunOS 4.X,
- when it's so terribly broken that it won't work under NIS (A flagship
- of Sun, remember...) ??? Why will Sun not commit to making a patch
- available to rpc.yppasswdd, but just offer the arrogant solution
- of upgrading to Solaris 2.0 ???
