I have always done it with SSL and it seems to work just
fine. I admit I have not done so with TLS.

Sun's own documentation says not to try to use connection pooling with
TLS. Ignoring that I've tried many times to get it to work, both with
grouper and with a shib 1.3 IdP. All without success. The VT library
works just fine right out of the box.

I thought the issue of the JNDI adapter was resolved some time
ago to allow for connection pooling? This involved the setting
of an environment variable in the grouper code enabling the pooling
built into the sun code. I also believe the sun jndi does support
ssl and connection pooling for ssl. What leads you to believe it
doesn't? What am i missing?

(this is my initial look, not RLBob's)

We are looking at Grouper as a possibly registry for our groups
presently supported by an LDAP directory and a RESTful webservice.
testing and planning, not yet installing. These are some random
we've encountered. Not complaining, just thought I'd let you know.

1) Jndi source adapter

The jndi classes from Sun do not support ldap connections using ssl or
tls very well. They do not support connection pooling, thereby
a lot of connection overhead. We wrote a source adapter using the
library from virginia tech - the one used by shibboleth. It works
a bit more efficiently.
