AAF has made a required URL Change. When you start using AAF Auto-Generated Configs and Certs, it will be covered.

However, in the mean-time, wherever you use
"AAF_NS." in AAF URLs, please change to "onap.org.osaaf.aaf."

Example:
aaf_url=https://AAF_LOCATE_URL/AAF_NS.service:2.0" becomes

aaf_url=https://AAF_LOCATE_URL/onap.org.osaaf.aaf.service:2.1"

(move to 2.1 isn't absolutely required, since AAF has Backward Compatible API, but is the most accurate)

Brian Freeman has tested this change for AAI, and others.
