Description of problem:
After upgrading to new samba packages, OS X clients cannot authenticate as guests making local public network shares inaccessible.
Version-Release number of selected component (if applicable):
Apr 18 08:14:06 Updated: samba-libs-4.2.10-6.el7_2.x86_64
Apr 18 08:14:07 Updated: samba-common-tools-4.2.10-6.el7_2.x86_64
Apr 18 08:14:07 Updated: samba-common-4.2.10-6.el7_2.noarch
Apr 18 08:14:07 Updated: samba-client-libs-4.2.10-6.el7_2.x86_64
Apr 18 08:14:07 Updated: samba-common-libs-4.2.10-6.el7_2.x86_64
Apr 18 08:14:09 Updated: samba-4.2.10-6.el7_2.x86_64
Immediately after upgrade without any configuration changes. Windows and Linux clients can mount and work with the shares as usual.
Steps to Reproduce:
1. Upgrade to latest EL 7.2 samba packages
2. Try to mount a guest mountable network share using OS X Yosemite
OS X clients fail to mount with a generic error: 'There was a problem connecting to the server "<address>".'
Share mountable and browsable.
First encounter on production CentOS 7 server. Downgrading back to following packages works around the problem:
Apr 18 09:08:01 Installed: samba-libs-4.2.3-12.el7_2.x86_64
Apr 18 09:08:01 Installed: samba-common-tools-4.2.3-12.el7_2.x86_64
Apr 18 09:08:01 Installed: samba-common-4.2.3-12.el7_2.noarch
Apr 18 09:08:02 Installed: samba-client-libs-4.2.3-12.el7_2.x86_64
Apr 18 09:08:02 Installed: samba-common-libs-4.2.3-12.el7_2.x86_64
Apr 18 09:08:02 Installed: samba-4.2.3-12.el7_2.x86_64
I have confirmed this on up-to-date RHEL 7 VM with the developer license using identical package versions and epochs including downgrading.
I have the same problem... We use our Samba fileserver for homedirs and profils in our Windows and Mac labs.
With this version of Samba, the Mac login session would lock-up and multiple 'smbd' with 100% CPU usage!
If I haden't notice this so quickly all our labs (Linux, Windows, Mac) would have been unuseable!
I grabbed the SRPMS from Fedora 24 testing and recompiled:
Everything works correctly now (CentOS 7.2).
This is affecting me as well. It appears that Debian has committed a fix to their packages last week:
The samba team also has committed a patch for this:
I am experiencing this problem on OS X hosts running 10.9-10.11. In the mean time, I'll need to compile srpms from the Fedora Project, which is not a great solution in the long run.
I have also file a bug report with CentOS, which can be viewed here:
