CONFIGURATION

DBI-specific options are described here. Shared options are described in the etc/RT_SiteConfig.pm file included in this distribution.

The example in the ``SYNOPSIS'' lists all available options and they are described below. See the DBI module for details on debugging connection issues.

dbi_driver
The name of the Perl DBI driver to use (e.g. mysql, Pg, SQLite).
server
The server hosting the database.
port
The port to use to connect on (e.g. 3306).
user
The database user for the connection.
pass
The password for the database user.
database
The database name.
table
The database table containing the user information to check against.
u_field
The field in the table that holds usernames
p_field
The field in the table that holds passwords
p_check
Optional. An anonymous subroutine definition used to check the (presumably hashed) passed from the database with the password entered by the user logging in. The subroutine should return true on success and false on failure. The configuration options "p_enc_pkg" and "p_enc_sub" will be ignored when "p_check" is defined.

An example, where "FooBar()" is some external hashing function:

    p_check => sub {
        my ($hash_from_db, $password) = @_;
        return $hash_from_db eq FooBar($password);
    },

Importantly, the "p_check" subroutine allows for arbitrarily complex password checking unlike "p_enc_pkg" and "p_enc_sub".

p_enc_pkg, p_enc_sub
The Perl package and subroutine used to encrypt passwords from the database. For example, if the passwords are stored using the MySQL v3.23 ``PASSWORD'' function, then you will need the Crypt::MySQL "password" function, but for the MySQL4+ password you will need Crypt::MySQL's "password41". Alternatively, you could use Digest::MD5 "md5_hex" or any other encryption subroutine you can load in your Perl installation.
p_salt
If p_enc_sub takes a salt as a second parameter then set it here.
d_field, d_values
The field and values in the table that determines if a user should be disabled. For example, if the field is 'user_status' and the values are ['0','1','2','disabled'] then the user will be disabled if their user_status is set to '0','1','2' or the string 'disabled'. Otherwise, they will be considered enabled.
