RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Pat Riehecky 2014-12-11 14:49:05 UTC 
Description of problem:
Firefox's debug log shows NTLM Native does not work as it cannot find ntlm_auth.

It appears that ntlm_auth is being called without $PATH set correctly

Version-Release number of selected component (if applicable):firefox-31.3.0-3.el6_6.x86_64


How reproducible:100%


Steps to Reproduce:
1.yum install samba-winbind-clients
2.export NSPR_LOG_FILE=/tmp/moz.log
3.export NSPR_LOG_MODULES=negotiateauth:10,nsHttp:10
4.tail -f /tmp/moz.log & firefox
5.log complains native NTLM doesn't work

Actual results:
log complains native NTLM doesn't work

Expected results:
correctly uses ntlm_auth helper program

Comment 2 Martin Stransky 2014-12-19 16:14:09 UTC 
From upstream bug https://bugzilla.mozilla.org/show_bug.cgi?id=554122#c7

With Firefox 21.0 this was *sporadically* working for me. It turns out to be trying to run "ntlm_auth" with no path:

7113  execve("ntlm_auth", ["ntlm_auth", "--helper-protocol", "ntlmssp-client-1", "--use-cached-creds", "--username", "dwmw2"], [/* 88 vars */]) = -1 ENOENT (No such file or directory)

If I run firefox from /usr/bin then it works; from elsewhere it doesn't.
Comment 3 Martin Stransky 2014-12-22 10:08:54 UTC 
Can you please test latest package? Firefox-31.3.0. It uses PR_CreateProcess() for the ntlm_auth launch and should consider PATH variable.
Comment 4 Martin Stransky 2014-12-22 10:11:30 UTC 
Ahh, sorry, I missed the version in comment 0.
Comment 5 Martin Stransky 2014-12-22 10:14:26 UTC 
Can you please run firefox + ntlm_auth with strace ($strace -o debug.txt firefox) and reproduce the problem and attach the debug.txt file here? Thanks!

Requested debug log

I've compressed it with xz as the raw file was a few Mb.
Comment 7 Martin Stransky 2014-12-22 16:08:13 UTC 
Ahh, sorry, it needs to be run as "$strace -f -o debug.txt firefox" because the auth command is called from separated process and strace does not follow fork by default. So please run the modified command and attach all files (debug.txt.XXX) where XXX is a proccess number. Thanks!

Comment 9 Martin Stransky 2014-12-22 16:33:22 UTC 
I guess you have ntlm_auth in /usr/bin and your PATH contains /usr/bin, right?
Comment 10 Pat Riehecky 2014-12-22 16:37:39 UTC 
Correct.

$ echo $PATH
/usr/krb5/bin:/usr/krb5/bin:/usr/lib64/qt-3.3/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin:/home/riehecky/bin

$ rpm -q samba-winbind-clients
samba-winbind-clients-3.6.23-12.el6.x86_64
Comment 12 Martin Stransky 2014-12-23 14:47:43 UTC 
Thanks, I'll ask you for testing when updated packages are available.
Comment 13 Martin Stransky 2015-01-19 15:58:39 UTC 
Should be fixed in latest update - firefox-31.4.0-1.
