Document differences between Li and Be auth-related config files

We have some old test suites running in a private lab, which are making things easier by editing etc/org.opendaylight.aaa.authn.cfg to set authEnabled=false so that restconf requests do not require authentication.
That does not work anymore for recent Beryllium snapshots.

I guess etc/shiro.ini has to be edited in line 78 to achieve analogous effect of disabling authentication.
But I have only found shiro.ini mentioned here [0], and I am still not sure what to write after equal sign.

Is there a wikipage I am missing?
