This is a huge win for us at work, because it makes handling sudo configurations significantly easier. Normally, you have to store the configuration in /etc/sudoers on every single box. With this, you can store your sudo configuration in LDAP, and have all of the sudo rules in a single centralized location. Update it once, and all configured machines will then pull it.
I've become a big fan of LDAP, and with sudo supporting it, I think that anyone using LDAP and not storing sudo information in LDAP is crazy.
