[Samba] self compiled samba domain member, jessie, pam config

Hi Rowland,

Thanks for the very quick reply. :-)

On the page you reference 
(https://wiki.samba.org/index.php/Libnss_winbind_links) it says:

# smbd -B | grep LIBDIR
    LIBDIR: /usr/local/samba/lib/

On my install, I need to use lower case b. Capitol doesn't work. Perhaps 
the wiki needs to be updated?

Anyway: I created the symlinks, ldconfig, all seemed to work. Your 
recipe for pam-auth-update also seems to work, I could enable winbind 
authentication in pam-auth-update.

And just for the record: kinit / klist both work, I can browse to my 
4.3.1 samba server from windows: \\servername and \\1.2.3.4, 
smbd/nmbd/winbindd are all three running.

However...logging on using ssh doesn't work, in syslog I
get:> Oct 26 20:43:34 meet winbindd[906]: [2015/10/26 20:43:34.110597,  0]

I could only find this rather old bugreport, that seems to be irrelevant 
now: https://bugzilla.samba.org/show_bug.cgi?id=11081

(note: unable to change to /usr/local/samba/var/cores/winbindd, however 
the directory exists...)

Ideas?

Ah, it is not mine, I stole it from the debian package :-D

How are you trying to log in with ssh ? I use it with plain passwords to 
the DC all the time and don't have any problems.

If that line is in place, I cannot logon. If I take it out, I can logon.

Is this normal..? (or..are you also seeing that?)
