Description of problem:
All NIS accounts are rejected from logging on the system.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Set up a RH 7.2 system on a brand new Athlon PC.
2.Select NIS access with a given NIS domain and server.
3.Reboot machine and attempt to log on using any NIS accounts.
Actual Results: All access are declined. System logs reveals
Expected Results: Successful log in.
The same set of NIS accounts works okay on a system installed with RedHat
7.1, using the same set up as above.
I believe I have now worked out the problem.
The authentication process has apparantly been changed in that
it will accept the first 8 characters as a valid password.
Before RH 7.2, the authentication will accept the first 8 characters
of a password as well as the full password if it is longer than 8
Under RH 7.2, if the full password longer then 8 characters is
supplied, login is rejected. The user has to enter the first 8
characters of a password to log on.
This poses an embarrassment in a mixed NIS environment.
