rlm_sql

rlm_sql(5)							 FreeRADIUS Module							rlm_sql(5)

NAME

       rlm_sql - FreeRADIUS Module

DESCRIPTION

       The  rlm_sql  module  provides  an SQL interface to retrieve authorization information and store accounting information.  It can be used in
       conjunction with, or in lieu of the files and detail modules.  The SQL module has drivers to support the following SQL databases:

	    db2
	    iodbc
	    mysql
	    oracle
	    postgresql
	    sybase
	    unixodbc

       Due to the size of the configuration variables, the sql module is usually configured in a separate file, which  is  included  in  the  main
       radiusd.conf via an include directive.

       The main configuration items to be aware of are:

       driver This variable specifies the driver to be loaded.

       server

       login

       password
	      These specify the servername, username, and password the module will use to connect to the database.

       radius_db
	      The name of the database where the radius tables are stored.

       acct_table1

       acct_table2
	      These specify the tables names for accounting records.  acct_table1 specifies the table where Start records are stored.  acct_table2
	      specifies the table where Stop records are stored.  In most cases, this should be the same table.

       postauth_table
	      The name of the table to store post-authentication data.

       authcheck_table

       authreply_table
	      The tables where individual Check-Items and Reply-Items are stored.

       groupcheck_table

       groupreply_table
	      The tables where group Check-Items and Reply-Items are stored.

       usergroup_table
	      The table where username to group relationships are stored.

       deletestatlesessions
	      This option is set to 'yes' or 'no'.  If you are doing Simultaneous-Use checking, and this is set to yes, stale sessions	(  defined
	      as sessions for which a Stop record was not received ) will be cleared.

       sqltrace

       sqltracefile
	      These two options are useful for debugging sql problems.	If sqltrace is set to yes, then all sql queries being executed are written
	      to the file listed in sqltracefile.  This is disabled in normal operation.

       num_sql_socks
	      The number of sql connections to make to the database.

       connect_failure_retry_delay
	      The number of seconds to wait before attempting to reconnect to a failed database connection.

       sql_user_name
	      This is the definition of the SQL-User-Name attribute.  This is set once, so that you can use %{SQL-User-Name} in the  SQL  queries,
	      rather than the nested username substitution.  This ensures that Username is parsed consistently for all SQL queries executed.

       default_user_profile
	      This is the default profile name that will be applied to all users if set.  This is not set by default.

       query_on_not_found
	      This  option  is	set to 'yes' or 'no'.  If set to yes, then the default user profile is returned if no specific match was found for
	      the user.

       authorize_check_query

       authorize_reply_query
	      These queries are run during the authorization stage to extract the user authorization information from the  ${authcheck_table}  and
	      ${authreply_table}.

       authorize_group_check_query

       authorize_group_reply_query
	      These queries are run during the authorization stage to extract the group authorization information from the ${groupcheck_table} and
	      ${groupreply_table}.

       accounting_onoff_query
	      The query to be run when receiving an Accounting On or Accounting Off packet.

       accounting_update_query

       accounting_update_query_alt
	      The query to be run when receiving an Accounting Update packet.  If the primary query fails, the alt query is run.

       accounting_start_query

       accounting_start_query_alt
	      The query to be run when receiving an Accounting Start packet.  If the primary query fails, the alt query is run.

       accounting_stop_query

       accounting_stop_query_alt
	      The query to be run when receiving an Accounting Stop packet.  If the primary query fails, the alt query is run.

       simul_count_query
	      The query to be run to return the number simultaneous sessions for the purposes of limiting Simultaneous Use.

       simul_verify_query
	      The query to return the detail information needed to confirm that all suspected connected sessions are valid, and are not stale ses-
	      sions.

       group_membership_query
	      The query to run to check user group membership.

       postauth_query
	      The query to run during the post-authentication stage.
