This behavior happens when there are no unprocessed approval requests.
I didn't want to steer this conversation but I've seen this before in other products from other vendors ...
On startup does adaxes attempt to contact all of my Domain Controllers?? I ask because I have over 300 located all over North America. And, as I mentioned, this has caused other applications to take an awful long time to start.
If not, I still don't know why adaxes takes 45 minutes or longer to become responsive on startup ... it really makes patching the system or making any changes to it extremely difficult.
Thanks.
