+=item bayes_sql_custom_query query 
+
+This option gives you the ability to create a custom SQL query to
+retrieve username.  In order to work correctly your query should
+return only one value, the desired username. In addition, there
+are several "variables" that you can use as part of your query,
+these variables will be substituted for the current values right
+before the query is run.  The current allowed variables are:
+
+=over 2
+
+=item _USERNAME_
+
+The current user's username.
+
+=item _DOMAIN_
+
+The portion after the @ as derived from the current user's username, this
+value may be null.
+
+=back
+
+The query must be one continuous line in order to parse correctly.
+
+Here is an example query, please note that it is broken up for easy
+reading, in your config it should be one continuous line.
