Subject: [PATCH AUTOSEL 4.9 18/27] cifs: set domainName when a domain-key is used in multiuser
Date: Wed, 4 Sep 2019 12:02:11 -0400 [thread overview]
Message-ID: <20190904160220.4545-18-sashal@kernel.org> (raw)
In-Reply-To: <20190904160220.4545-1-sashal@kernel.org>
From: Ronnie Sahlberg <lsahlber@redhat.com>
[ Upstream commit f2aee329a68f5a907bcff11a109dfe17c0b41aeb ]
RHBZ: 1710429
When we use a domain-key to authenticate using multiuser we must also set
the domainnmame for the new volume as it will be used and passed to the server
in the NTLMSSP Domain-name.
