In fact, yes, I too had to copy some files around, but that was more 
than easy.

I did the same with smbpasswd.

No need for that in my case, but I didn't choose avahi in "make config".

Not sure what you mean.



In any case, I had samba34 working in a little more than a few minutes, 
with users still accessing shares, XP machines still doing domain logons 
and the new W7 box integrated at first try.

So far so good, it seemed, but it was not so.



First, I noticed profiles could not be copied back on the server at 
logoff: a quick search pointed to full_audit being buggy and in fact 
removing it turned out to be the correct workaround.
What I find strange is that it is deamed as not working in 3.4.7, but 
corrected in 3.4.8; this is evidently not true.
Later I upgraded to 3.4.9, but had no time to test it again.
I will ASAP and eventually report on the Samba newsgroup.



The second problem is harder: pam_smb stopped working, so I had domain 
logons and file sharing ok, but any other service rejecting users.
I could not come to any solution to this; I even tried pam_smbpass and 
setting up winbindd, but to no avail.
Time was not on my side, so I ended up putting every password into the 
UNIX database and forget about PAM for the moment.
However I'll have to fix this soon, so I'm in search of any hint on how 
to debug this.
I tried putting "debug" next to pam_smb_auth.so in /etc/pam.d/*, but 
this didn't help much.

Using Postgres (as an example) I get in my logs:
xxxxxx pamsmbd[93053]: cache_check: no entry
xxxxxx pamsmbd[93053]: server: remote auth user unix:yyyyy nt:yyyyy 
NTDOM:ZZZZZZ PDC:XXXXXX BDC:XXXXXX
xxxxxx postgres[16385]: pamsmbd: Got something back... 3
xxxxxx pamsmbd[93053]: cache_check: no entry
xxxxxx pamsmbd[93053]: server: remote auth user unix:yyyyy nt:yyyyy 
NTDOM:ZZZZZZ PDC:XXXXXX BDC:XXXXXX
xxxxxx postgres[16387]: pamsmbd: Got something back... 3

but then:

psql: FATAL:  PAM authentication failed for user "yyyyy"
FATAL:  PAM authentication failed for user "yyyyy"

In the meantime, I get absolutely nothing in /var/log/samba34/log.smbd.


Any hint?
