MID server auto upgrade issue

[Mahesh23]

Hello all,

During servicenow upgrades MID server failed to upgrade stating "Interactive authentication required" error because of missing permission(s)." in the wrapper log. Concerned with this, is my query below 

In order to access MID server host from servicenow mid_server role is necessary similarly is there any necessary role that a user needs to have at the host to connect with servicenow.

Thanks in advance

We discovered that the application was trying to start before our LDAP connections were established and systemd wasn't able to find our application user.  We ended up putting the user in the /etc/passwd file to get around this issue.

We have created a PolicyKit Rule to mitigate this error. The mid server user is given access to stop and start the systemctl service:

cd /etc/polkit-1/rules.d
vim 10-service-auth.rules
 
polkit.addRule(function(action, subject) {
    if (action.id == "org.freedesktop.systemd1.manage-units" &&
            subject.user == "servicenow") {
            var serviceName = action.lookup("unit");
            if (serviceName.indexOf("mid") == 0) {
                    return polkit.Result.YES;
            }
    }
});
