RHBA-2015:1366 - Bug Fix Advisory

Topic

Updated cifs-utils packages that fix one bug are now available for Red Hat
Enterprise Linux 6.

Description

The Server Message Block/Common Internet File System (SMB/CIFS) protocol is a
standard file sharing protocol widely deployed on Microsoft Windows machines.
The cifs-utils packages contain tools for mounting shares on Linux using the
SMB/CIFS protocol. The tools in this package work in conjunction with support in
the kernel to enable mounting a SMB/CIFS share onto a client and use it as if it
were a standard Linux file system.

This update fixes the following bug:

• Previously, attempts to mount a CIFS share failed when the system keytab was

stored in a non-default location specified using the default_keytab_name setting
in the /etc/krb5.conf file, even when the user provided the correct Kerberos
credentials. However, mounting succeeded when default_keytab_name pointed to the
default /etc/krb5.keytab file. The cifs.upcall helper process has been modified
to respect non-default keytab locations provided using default_keytab_name. As a
result, CIFS mount now works as expected even when the keytab is stored in a
non-default location. (BZ#1080482)

Users of cifs-utils are advised to upgrade to these updated packages, which fix
this bug.
