Hi,
I'm trying to put my samba to authenticate users into a mysql database.
I've started to use passdb and I did mapped the main fields and also did
some change at pdb_sql.c code to match my needs.
Well, the problem is that I can't found a way to use crypt passwords
with mysql using pdb_mysql, actually the type of passwords I'm allowed
to use are "plain password", "lanmanager password" or "nt password". By
the way I just could use "plain password", the other ways doesn't
authenticate, just generate passwords.
Since I think that to make pdb_mysql to work with crypt password will
need much more enforces changing source code, I prefer to find another way.
Looking at google I saw that I could use pam as authenticate method
telling pam to look at mysql database using pam_mysql module but that
solution doesn't work.
I did disabled pdb authenticate method and set "encrypt passwords =
no","obey pam restrictions = yes","pam password change = yes" which are
the needed changes I found at a lot of docummentation.
I did setup pam.d/samba like the guides I've found:
auth required pam_mysql.so user=dbuser passwd=dbpass db=users
table=users usercolumn=login crypt=0 passwordcolumn=password
account required pam_mysql.so user=dbuser passwd=dbpass db=users
table=users usercolumn=login crypt=0 passwordcolumn=password
password required pam_mysql.so user=dbuser passwd=dbpass db=users
table=users usercolumn=login crypt=0 passwordcolumn=password
session required pam_mysql.so user=dbuser passwd=dbpass db=users
table=users usercolumn=login crypt=0 passwordcolumn=password
If I try to login using no pdb method and setting up pam parameters that
what I get from smbd.log:

It appears like pam was not even called so the backend that samba try to
use is smbpasswd.
I did add my username to smbpasswd file ant try to login again and now
that's work.
So, what I want to know is how I can make my users authenticate by mysql
using crypt password?
Is there a way to make pdb_mysql to use crypt passwords? If not, how can
I put pam to do the authenticate?
Any advice would be aprreciated.
Tks,
Claudinei Matos
