Package: samba-common-bin
Version: 2:4.9.11+dfsg-1
Severity: normal

Dear Maintainer,

* What led up to the situation?

upgrade from stretch to buster

* What exactly did you do (or not do) that was effective (or ineffective)?
diverted testparm and replaced it with script that called 
"samba-tool testparm"   

the postinst checks for role of samba _after_ a plain testparm call
which fails because it is not supposed to be used on ad-dc
