Here is a simple example of this (well, this example uses the jdbc adapter, 
but for JNDI: change name of class and file to MyGrouperJndiSourceAdapter, 
and the name of the superclass to GrouperJndiSourceAdapter):

https://wiki.internet2.edu/confluence/display/GrouperWG/Example+of+customizing+the+subject+API+source+adapter

    *  Download the latest grouper 1.4 branch
          o cvs 
-d:pserver::/home/cvs/i2mi
 login
          o cvs 
-d:pserver::/home/cvs/i2mi
 export -r GROUPER_1_4_BRANCH grouper
    * In grouper dir, run: ant dist
    * Start the database (hsql in this case, could be mysql/postgres/oracle 
also):
          o F:\temp\grouper1.4\bin>java -cp ..\lib\jdbcSamples\hsqldb.jar 
org.hsqldb.Server -database.0 file:grouper -dbname.0 grouper
    * Add tables: (unix) bin> gsh.sh -registry -runscript     (windows): 
bin>gsh -registry -runscript
          o (note: this is using hsql, you can do a similar thing on mysql or 
postgres or oracle)
          o You should now be able to browse the DB with hsqlManager or 
whatever tool you use to admin the db
          o (hsql) bin>java -cp ..\lib\jdbcSamples\hsqldb.jar 
org.hsqldb.util.DatabaseManager -url jdbc:hsqldb:hsql://localhost/grouper
    *
    * Check tables:  bin> gsh.sh -registry -check
          o Should output: NOTE: database table/object structure (ddl) is up 
to date
    * Start gsh and add a subject: bin> gsh.sh
      gsh 10% addSubject("mchyzer", "person", "Chris Hyzer")
      hibernatesubject: id='mchyzer' type='person' name='Chris Hyzer'
      gsh 11% SubjectFinder.findById("mchyzer", "person").getAttributes()

       java.util.HashMap: {LFNAME=[null], LOGINID=[null]}

      gsh 12% exit
    *  Make a directory under src/grouper called "poc"  (proof of concept)
    * Add a java source file of this name 
"src/grouper/poc/MyGrouperJdbcSourceAdapter.java" with these contents:

      /*
       * @author mchyzer
       * $Id$
       */
      package poc;

      import java.util.Set;

      import org.apache.commons.lang.StringUtils;

      import edu.internet2.middleware.grouper.subj.GrouperJdbcSourceAdapter;
      import edu.internet2.middleware.grouper.util.GrouperUtil;
      import edu.internet2.middleware.subject.Subject;
      import edu.internet2.middleware.subject.SubjectNotFoundException;
      import edu.internet2.middleware.subject.SubjectNotUniqueException;

      /**
       *
       */
      public class MyGrouperJdbcSourceAdapter extends 
GrouperJdbcSourceAdapter {

        /**
         * as an example, concatenate two attributes together, store as a 
third attribute
         * @param subject
         */
        private void decorateSubject(Subject subject) {
          if (subject != null) {
            String idNameLoginid = subject.getId() + " " + subject.getName() 
+ " "
              + 
StringUtils.defaultString(subject.getAttributeValue("LOGINID"));
            subject.getAttributes().put("idNameLoginid", idNameLoginid);
          }
        }

        @Override
        public Subject getSubject(String id) throws SubjectNotFoundException,
            SubjectNotUniqueException {
          Subject subject = super.getSubject(id);
          decorateSubject(subject);
          return subject;
        }

        @Override
        public Subject getSubjectByIdentifier(String id)
            throws SubjectNotFoundException, SubjectNotUniqueException {
          Subject subject = super.getSubjectByIdentifier(id);
          decorateSubject(subject);
          return subject;
        }

        @Override
        public Set<Subject> search(String searchValue) {
          Set<Subject> subjectSet = super.search(searchValue);
          for (Subject subject : GrouperUtil.nonNull(subjectSet)) {
            decorateSubject(subject);
          }
          return subjectSet;
        }

      }


      * Edit the sources.xml, and instead of:
       <source 
adapterClass="edu.internet2.middleware.grouper.subj.GrouperJdbcSourceAdapter">
          <id>jdbc</id>
      Change it to:
        <source adapterClass="poc.MyGrouperJdbcSourceAdapter">
          <id>jdbc</id>
    * Do another    "ant dist"  from GROUPER_HOME
    * Start gsh from the bin dir, search for the subject again, see the new 
attribute: idNameLoginid

      gsh 0% SubjectFinder.findById("mchyzer", "person").getAttributes()
      java.util.HashMap: {LFNAME=[null], idNameLoginid=mchyzer Chris Hyzer , 
LOGINID=[null]}
      gsh 1%

    * Note, after major upgrades of Grouper versions, you should test this to 
make sure it is still accurate...
