Hi,
In which version of EPM add-in are you running. In SP16 patch 01 its working as expecting.
Can you try :
- 1.start IE -> Tools -> Internet Options -> Security
- 2.In the security tab
Click button "Custom level" in "Internet" zone and change the logon model in "User Authentication".
Click button "Custom level" in "Local intranet" zone and change the logon model in "User Authentication".
Add your web service site, for example https://localhost:8080/oSoft, to trusted site list.
- Select option "Save Password" in popup window.
Hope it works..
regards,
Raju
