How to work "Allow Automatic Generation of API Key"

Hi,
We configured "Allow Automatic Generation of API Key" in SDP to automatic login with SDP mobile app by all users, but error me and need to generate API Key. I need to access SDP by mobile app without generate API Key one by one. What should I do?

I attched my configuration and error.
SDP version: 11.1.15
DB: MS SQL

Thanks for helping
