+PDB MySQL plugin for samba v1.1
+--
+
+Building
+=========
+Before you can build the plugin, set the variable SAMBA_SRC in Makefile to the
+path containing the samba sources. This is usually the 'source' directory in
+the samba tarball or CVS.
+
+Next, type make, and then 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.

+Readme for samba pdb xml 0.5
+--
+This module requires libxml2 to be installed.
+
+The usage of pdb_xml is pretty straightforward. To export data, use:
+
+pdbedit -e plugin:/usr/lib/samba/pdb_xml.so:filename
+
+(where filename is the name of the file to put the data in)
+To import data, use:
+
+pdbedit -i plugin:/usr/lib/samba/pdb_xml.so:filename -e <current-pdb>
+
+Where filename is the name to read the data from and <current-pdb> to put it in.
