Description jbrav.hax 2013-10-16 07:39:25 UTC
Using smbclient with an auth file (-A) and valid logins to a domain is resulting in LOGIN_FAILED for all but one system (Win 2k12 server.) However if I use the same credentials with a -U flag I am able to log into the systems without issue.

I also tested v3.6.19 with the same auth file against the same systems and had no issues whatsoever.

I downloaded and compiled the source from the samba.org website.

This also appears to affect v4.0.9 and v4.1.0 (No other v4 were tested.)

cd samba/source3
make -j8
no errors during build.

I copy the smbclient bin to the home directory and run it. I do receive an error about the smb.conf but I am not concerned with that since it doesn't appear to affect using the binary with the -U option so I assume it should work with the -A option and a properly formatted auth file.

Authfile - Domain User:

The authfile above does not work however the auth file below works without issue:

Auth file - Local User:

Systems connecting to:
Windows 2012 Server 64-Bit
Windows 2008 Server 64-Bit
Windows 2003 Server 32-Bit
Windows 8 64 bit
Windows 7 32-Bit
Windows XP 32-Bit

Command used:
./smbclient -A test //IP/C$ (Only works agains the Win2k12 set up as the DC)

./smbclient -U brav0hax/topdog%P@ssW0rd //IP/C$ (Works with all systems without issue)
