I've managed to get Windows AD authentication working with the REST API, but I'm finding the logon times to be very sporadic.
Some calls to /biprws/logon/adsso can be as fast as two seconds; other times it can be up to a minute.
I also have Win AD SSO working in BI Launch Pad; that can take up to 10 seconds at worst, but never as long as adsso in WACS.
Any suggestions on how to speed up adsso?
