Hi Michael,

I added the following line of code in the setupEnvironment() method of the JNDISourceAdapter class.

environment.put("com.sun.jndi.ldap.connect.pool", "true");

Then since I'm using SSL, I added the following to the java command line.

-Dcom.sun.jndi.ldap.connect.pool.protocol="plain ssl"

How did you enable connection pooling? Did you do something equivalent to
adding -Dcom.sun.jndi.ldap.connect.pool="true" to the java commandline? Or something

I recall the connection pooling issue with the JNDISourceAdapter being brought up before, but I don't see any Jira issues on that. So I thought I would share some results. Simply by adding connection pooling to the JNDISourceAdapter, I'm seeing a significant performance improvement while making repeated calls to Member.getSubject(). For instance, for a group with 120 members, retrieving the Subject objects for all 120 members resulted in a 60% performance improvement while using connection pooling.
