JDBC and JNDI sources have two options each. For JDBC, if you can make a table/view where each subject is represented as one row of the view, then the more powerful GrouperJdbcSourceAdapter2. One of the major advantages is that if you enter in a phrase in the subject search, e.g. "John Smith", then it will search for records which have John and Smith in them (case insensitive), whereas the GrouperJdbcSourceAdapter will look for the whole string "John Smith" and will not return a record for "John L Smith". For JNDI, UW contributed a source adapter which sohuld should give better performance.
As of Grouper 2.0, Grouper stores additional data about subjects that are used by Grouper to search and sort a list of members. Each source must be configured for at least one search attribute and one sort attribute.
