Hi Avi,
Are you logging into the ENTM UI and face slow response there?
If so - are you using AD as your user store?
And if so - have you checked to see if your AD is configured to work with Global Catalog?
And so far so good - have you set the AD Global Catalog ports instead of the normal ports for the ac-env?
More than that - are you using SSL for the connection or non-SSL?
Do let us know the answers to the above so we can help you in getting this resolved.
Regards,
Amit.
