Re: Confused on best secuirty method...

You can get information on Cyrul SASL from their website..
There's a 'SASL Programmer's Guide' one the site, which may be useful.

For information about the protocol itself see RFC-2222

We (at GLOBUS ) are using an OpenSSL/GSI/SASL/OpenLDAP stack. You can find
more information at www.globus.org
