Earlier I'd setup Icinga in HA with separate mysql DB,integrated it with AD server and everything was working perfectly fine. Recently our AD servers were changed and this requires us to update the LDAP configuration on Icinga.
I then updated the AD information in Icinga console at Configuration-->Application pane and created resource and new user backend group in authentication pane with which all the new users were discovered and I thought its done.
But once I stopped my old AD servers, the Icinga application was not able to connect with the RDS instance and gave me error on the console:-
SQLSTATE[HY000]  Unknown MySQL server host 'xxxxxxxxxxxxxxxxxxxxxxxxx' (110)
Even I'm not able to login with my Icinga admin credentials post stopping the AD instance.
Can anyone please suggest how that can be fixed? What is the thing that I'm missing here.
Kindly post your suggestion and do revert in case of any query.
