Description Nalin Dahyabhai 2006-01-27 11:36:25 EST
+++ This bug was initially created as a clone of Bug #164794 +++ Description of problem: Running Red Hat Enterprise Linux AS release 4 (Nahant Update 1) using kerberos authentication against Microsoft Active directory, seems to been broken compared to previous Red Hat releases (like AS3 U5) regarding the use of su as root. If I logon with root (console or via ssh), I'm not able to su to a "normal" local user account : ]# su - guest1 su: incorrect password Version-Release number of selected component (if applicable): Red Hat Enterprise Linux AS release 4 (Nahant Update 1) coreutils-5.2.1-31.1 How reproducible: Logon as root via SSH or console, perform su for a local account like guest1 Actual results: Su does not ask for a password and despite "minimum_uid = 500" in the krb5.conf file (user guest1 has uid 504), "it" contacts the MS-AD servers trying to authenticate the user without asking for a password. I've disabled SE-Linux to rule out problems from that side, but to no avail. Comparing the /etc/pam.d/su file with the one on a AS3-U5 server reveals leads, except for the extra pam_selinux.so lines. When disabling kerberos authentication, via authconfig, su works like a charm, no password needed like expected. Expected results: A local user shell for guest1 or otherwise a apropriate error message Additional info: Enabling "Local authorization is sufficient" via authconfig, enables su for root on local accounts while kerberos authentication is enabled -- Additional comment from firstname.lastname@example.org on 2005-08-01 15:01 EST -- This looks less like an enhancement, and more like something that we really ought to have on the proposed list. http://intranet.corp.redhat.com/ic/intranet/RHELUpdateContentProcess.html -- Additional comment from email@example.com on 2005-08-02 08:32 EST -- Changing component and reassigning. -- Additional comment from firstname.lastname@example.org on 2005-08-03 15:36 EST -- This is a sort-of duplicate of bug #140325, which was filed against RHEL 3. -- Additional comment from email@example.com on 2005-10-19 13:26 EST -- This also affects cronjobs, as I reported in Bug #144064. That was reported on FC3, which is more-or-less RHEL 4.
