Anyone please help me in understanding the kafka ssl principal mapping rule. for example in the following mapping rule RULE:^CN=(.*?),OU=(.*?),O=(.*?),L=(.*?),ST=(.*?),C=(.*?)$/$1@$2/, what is the significance of ".*?" inside parenthesis ?
my distinguished name is "CN=kafka(S12345),OU=Services,DC=ET-GROUP,DC-etit" I have to extract S12345 inside parenthesis as short name. what rule should i use ?
