[Pkg-ltsp-devel] Bug#482553: ldm: password change doesn't work

[John S. Skogtvedt]

Package: ldm
Version: 2:2.0.3-1~40.etch.0
Severity: normal


When trying to log in as a user with an expired password,
I experienced the following problems:

1) ldm first prompted for new password, and then prompted again (to confirm).
  After that it got stuck - I could enter text, but nothing happened.
2) ldm doesn't check if the new password is equal to the old password.
  If it is, then the password won't be succesfully changed.
3) (with 1 and 2 fixed) ldm incorrectly zeros the password,
  so that the user has to enter the new password again to log in after
  a password change.

I have attached a patch which should fix these problems.

Steps to reproduce:
1) Expire a users password on the server.
2) Attempt to log in as the user with ldm.
