Is slapo-ppolicy only supported in OpenLdap 2.3?  The openldap.org man pages
only lists slapo-ppolicy for version 2.3 and not for 2.2:

http://www.openldap.org/software/man.cgi?query=slapo-ppolicy&apropos=0&sektion=0&manpath=OpenLDAP+2.3-Release&format=html

Can someone point me to a page showing the differences between 2.2 and 2.3?
I found a changelog, but it only pertains to 2.3 minor releases.

Thanks,
Victor
