Unable to get AD group listing in Spark

Hi All,

My Company has one Domain Controller & working Spark Instance which is showing all the Groups in AD in Spark.

Today I created an another instance of Spark & joined AD. All is well but it is not showing Group or user listing in Spark whereas I am getting that listing in Admin console of newly created instance.

I am using Latest Openfire & latest Spark.

Please help me out.

Thanks,

Rocky
