I setup my share right, followed all the instructions, set the /etc/pam.conf entry.  Couldn’t get into my share, and my password wouldn’t work.

I found that you can test your PAM mapping like so:

smbutil login –c username

But that gave me:

Keychain entry not found.

Ok, had to do a little searching…  found out that you can SET THE STORED PASSWORD FOR SMB!  Duh!  Why didn’t I think of that in the first place?  LOL!

All you need to do is this:

smbutil login username@server

It will ask you for a password and suddenly your login from windows will work! Nice!

Keep in mind, that is assuming your server is setup in workgroup mode, joined to your workgroup not the domain.  I think you would just specify “username@netbiosdomain” in that case.

Check the /etc/pam.conf has the smb line:

   other    password required    pam_smb_passwd.so.1    nowarn

If not, add that to the end of the file.  If you, check /var/smb/smbpasswd you should also see a line for your account with a hashed password listed.  In my case, I had my username and an ID listed, but not hashed password.  I didn’t have the line in pam.conf.  After I added it, I had to run the passwd username command on my account, which generated the smb password and inserted it into the smbpasswd file. Then the error about password not being correct went away and I could get in from Windows.  (Windows 7 too! With the “NTLMv2 if negotiated” option in policy.)
