Description Ed Friedman 2002-09-10 18:05:34 UTC

From Bugzilla Helper:
User-Agent: Mozilla/4.79 [en] (X11; U; Linux 2.4.18-10 i686)

Description of problem:
passwd tries to change the password in the NIS passwd database, even when the
/etc/nsswitch.conf entry for passwd is set to files only.  The end result is
that no users can change their passwords on the local machine if their login
name exists in the NIS database.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1.Configure a machine with NISDOMAIN set and with passwd in nsswitch.conf set to
files only
2.Create a user on the local machine with a login name identical to an existing
NIS login name
3.Login as that user on the local machine and try to change the password on that
local machine using the passwd command
	

Actual Results:  It is impossible to change the local password because the
passwd command tries to change the password of the NIS login with the same name

Expected Results:  The local password should have been changed.

Additional info:

In 7.3, the permissions of /usr/bin/yppasswd are now 500, whereas they used to
be 555 in previous RedHat versions.  It appears that someone is trying to
phaseout the yppasswd command by having passwd do an intelligent guess as to
what password should be changed.  However, if that is the case, when
nsswitch.conf has passwd set to files only, then passwd should not be invoking
yppasswd.

Comment 1 Tomas Mraz 2005-03-24 19:30:38 UTC

Password changing is not affected by /etc/nsswitch.conf but by the nis option of
the pam_unix.so module in the /etc/pam.d/system-auth file. The problem of
changing NIS password when an user is in the local passwd file is fixed in the
current Fedora Core release.
