Description David Mansfield 2015-06-18 15:40:57 UTC

+++ This bug was initially created as a clone of Bug #1202347 +++

Description of problem:

Computers can no longer connect to a samba4 domain member server
with username/password authentication.  Only kerberos authentication is accepted.

Tried an android client as well.  Error is "A lock request  specified an invalid locking mode , or conflicted with an existing file lock."

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

samba-4.2.2-0.fc22.x86_64

How reproducible:

Always

Steps to Reproduce:
1. smbclient //server/share -U user -W DOMAIN


Actual results:
NT_STATUS_LOCK_NOT_GRANTED.

Expected results:
Normal smbclient session.

Additional info:
smbclient -k //server/share works fine. 

sssd is being used.

"security = ads" is being used.

same exact configuration works on samba-4.1.17-1.fc21.x86_64 on fedora 21.

Here's my smb.conf:

[global]
	workgroup = MYDOMAIN
	kerberos method = secrets and keytab
	log file = /var/log/samba/%m.log
	realm = MYDOMAIN.COM
	security = ads

[shared]
	comment = shared
	path = /srv/shared
	read only = no
	browseable = no

Comment 1 Gregory Lee Bartholomew 2015-08-21 19:53:33 UTC

Same here.  I just upgraded my server to Fedora 22 and I now get the NT_STATUS_LOCK_NOT_GRANTED error when trying to connect from my linux workstation.  My setup was working previously.

I am running samba-4.2.2-1.fc22.x86_64.

When I try to connect from Windows workstations, I get the following in /var/log/samba/log.smbd:

Comment 2 Gregory Lee Bartholomew 2015-08-21 20:31:46 UTC

Sorry, it looks like the garbage from the Windows connection attempts was do to the cifs/server.domain@REALM principle not being present in my linux server's keytab.

Adding "cifs/server.domain" to the computer account's servicePrincipleName entry in AD with the ADSI Edit tool and running:

net -U <domain user> ads keytab add cifs/server.domain@REALM

on my linux server seems to have fixed that.  It was working previously, but maybe it was using NTLM.

So, as with the reporter, I can connect via kerberos authentication (linux or windows client), but I cannot connect with a username and password.

I get NT_STATUS_LOCK_NOT_GRANTED from my linux client.

Comment 3 Gregory Lee Bartholomew 2015-08-21 20:55:00 UTC

A second issue that I am having with my samba server after upgrading to Fedora 22 is that if I try to connect using the local samba user:

Unix username:        root

My server instantly and completely locks up.  I had tail -f /var/log/samba/log.smbd running in an ssh terminal and logging set to 9 when I attempted to connect with the local user.

No lines were printed to the log file and the server completely froze.  I had to hard poweroff the server to get it going again.

I'm not sure if this is a "supported" configuration, but I had created that local user before I joined my samba server to the AD domain as a domain member.  Before I upgraded, I was able to connect to the samba server with \\VM-00\Administrator (where "root = Administrator" was in smbusers) or with an active directory account.

I found the ability to log onto my samba server with both the local samba user or a domain account very useful.  I was even able to use identical Administrator passwords on my Windows workstations and on my samba server and the windows clients would auto-authenticate to the samba server when I was logged onto them with the local Administrator account.  This was extremely convenient for installing software on the Windows machines which I always do with the local Windows Administrator account.

Because my production linux server now completely hangs/halts whenever I log onto one of my Windows workstations as Administrator, this is a pretty serious bug for me (I have network neighbourhood shortcuts defined in the local Administrator account's profile on some of my workstations -- just logging onto them with Administrator takes down my server because the network neighbourhood links automatically attempt to connect when I start Windows Explorer).

Comment 4 Guenther Deschner 2015-08-31 10:46:16 UTC

You are not running winbindd, right? There will be an update to 4.2.3 soon which will have this fixed.

Comment 5 David Mansfield 2015-08-31 14:58:56 UTC

Correct. We don't have winbind but we are using sssd with ad backend.

Comment 6 Gregory Lee Bartholomew 2015-08-31 15:39:22 UTC

I'm not running winbind either.

Also, regarding the hard lockups that I am experiencing, I commented out the "root = Administrator" mapping that I had in smbusers, and I changed the permissions on my shares so that I could only connect with domain accounts, and that seems to have helped greatly, but I did still get one lockup when I tried to connect to one particular share (I only tried once; I am wary of trying again because I need this server to stay online right now).  The share that caused my server to hang with 100% CUP usage was my "CD" share which is unique in that it has a preexe line defined that points to the following bash script:

[cd]
...
preexec = /etc/samba/iso-mount.sh &>/dev/null
...

iso-mount.sh contains:

#!/usr/bin/bash
# vim:set ts=3:

set -e
# exec &>/dev/null
cd /export/archive/cd
for i in *.iso; do
   BASE=${i%%.iso}
if [ ! -e $BASE ]; then
   mkdir $BASE
fi
if ! mountpoint -q $BASE; then
   mount -o ro,loop $i $BASE
fi
done

The script used to work before the upgrade.  I just realized though, I should probably change "preexec" to "root preexec" since I am connecting with a domain account now.  Maybe the hard lockup is due to samba not being able to call mount???

I'll keep an eye out for the update.  Thanks!
