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/
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
WARNING: since the password for the mysql user is stored in the smb.conf file, you should make the the smb.conf file readable only to the user that runs samba. This is considered a security bug and will be fixed soon.
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:plain 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.
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:plain pass column' to the name of the column containing the plaintext passwords.
If you use encrypted passwords, set the 'identifier:plain pass column' to 'NULL' (without the quotes). This is the default.
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
