[PATCH 2/4] [CIFS] Don't ignore errors on encrypting password in SMBTcon
From: Steve French
Date: Fri Mar 27 2015 - 01:28:51 EST
Although unlikely to fail (and tree connect does not commonly send
a password since SECMODE_USER is the default for most servers)
do not ignore errors on SMBNTEncrypt in SMB Tree Connect.
