Passdb MySQL plugin
Building
To build the plugin, run make bin/pdb_mysql.so
in the source/ directory of samba distribution.
Next, copy pdb_mysql.so to any location you want. I
strongly recommend installing it in $PREFIX/lib or /usr/lib/samba/
Configuring
This plugin lacks some good documentation, but here is some short info:
Add a the following to the passdb backend variable in your smb.conf:
passdb backend = [other-plugins] plugin:/location/to/pdb_mysql.so:identifier [other-plugins]
The identifier can be any string you like, as long as it doesn't collide with
the identifiers of other plugins or other instances of pdb_mysql. If you
specify multiple pdb_mysql.so entries in 'passdb backend', you also need to
use different identifiers!
Additional options can be given thru the smb.conf file in the [global] section.
identifier:mysql host - host name, defaults to 'localhost'
identifier:mysql password
identifier:mysql user - defaults to 'samba'
identifier:mysql database - defaults to 'samba'
identifier:mysql port - defaults to 3306
identifier:table - Name of the table containing users
Names of the columns in this table(I've added column types those columns should have first):
identifier:logon time column - int(9)
identifier:logoff time column - int(9)
identifier:kickoff time column - int(9)
identifier:pass last set time column - int(9)
identifier:pass can change time column - int(9)
identifier:pass must change time column - int(9)
identifier:username column - varchar(255) - unix username
identifier:domain column - varchar(255) - NT domain user is part of
identifier:nt username column - varchar(255) - NT username
identifier:fullname column - varchar(255) - Full name of user
identifier:home dir column - varchar(255) - Unix homedir path
identifier:dir drive column - varchar(2) - Directory drive path (eg: 'H:')
identifier:logon script column - varchar(255) - Batch file to run on client side when logging on
identifier:profile path column - varchar(255) - Path of profile
identifier:acct desc column - varchar(255) - Some ASCII NT user data
identifier:workstations column - varchar(255) - Workstations user can logon to (or NULL for all)
identifier:unknown string column - varchar(255) - unknown string
identifier:munged dial column - varchar(255) - ?
identifier:uid column - int(9) - Unix user ID (uid)
identifier:gid column - int(9) - Unix user group (gid)
identifier:user sid column - varchar(255) - NT user SID
identifier:group sid column - varchar(255) - NT group ID
identifier:lanman pass column - varchar(255) - encrypted lanman password
identifier:nt pass column - varchar(255) - encrypted nt passwd
identifier:plaintext pass column - varchar(255) - plaintext password
identifier:acct control column - int(9) - nt user data
identifier:unknown 3 column - int(9) - unknown
identifier:logon divs column - int(9) - ?
identifier:hours len column - int(9) - ?
identifier:unknown 5 column - int(9) - unknown
identifier:unknown 6 column - int(9) - unknown
Eventually, you can put a colon (:) after the name of each column, which
should specify the column to update when updating the table. You can also
specify nothing behind the colon - then the data from the field will not be
updated.
Using plaintext passwords or encrypted password
I strongly discourage the use of plaintext passwords, however, you can use them:
If you would like to use plaintext passwords, set 'identifier:lanman pass column' and 'identifier:nt pass column' to 'NULL' (without the quotes) and 'identifier:plaintext pass column' to the name of the column containing the plaintext passwords.
If you use encrypted passwords, set the 'identifier:plaintext pass column' to 'NULL' (without the quotes). This is the default.
Getting non-column data from the table
It is possible to have not all data in the database and making some 'constant'.
For example, you can set 'identifier:fullname column' to :
CONCAT(First_name,' ',Sur_name)
Or, set 'identifier:workstations column' to :
NULL
See the MySQL documentation for more language constructs.
