I first noticed the problem when I went to print a document on a printer that is shared by a Windows 7 machine. It normally prompts me for my password but it would not accept the password -- it kept asking for it over and over. In the CUPS error log I see:
Code: Select all
E [15/Apr/2016:13:51:42 -0500] [Job 3440] Session setup failed: NT_STATUS_ACCESS_DENIED
E [15/Apr/2016:13:51:42 -0500] [Job 3440] Session setup failed: NT_STATUS_ACCESS_DENIED

E [15/Apr/2016:13:51:42 -0500] [Job 3440] Tree connect failed (NT_STATUS_ACCESS_DENIED)
I then tried:
Code: Select all
smbclient -L //WINPC -U myuser
Code: Select all
NTLMSSP packet check failed due to short signature (0 bytes)!
NTLMSSP NTLM2 packet check failed due to invalid signature!

So it looks like something in Samba broke in this latest update. I have a Solaris box that I can still connect to fine, so Samba isn't totally broken, but it appear to be for connecting to Windows 7 at least. Can someone else test this on their network to a Windows 7 box? Does anyone know what changed in Samba for this latest update? Thanks.
