Anything else you need to do?
Created user, put in Admins group, gave login as mobile device, added password, added mobile device object, entered the Device ID as I see it in the app, added the user there, gave it all rights.
I don't see where the device ID went so I can't verify I entered it correctly.
Error:
199 13.09.2015 16:30:35 SECURITY [redacted] 128 [redacted] Mobile device login as user "[redacted]" failed with error code 2 (client info: n/a)
It didn't like the password. I entered the LastPass generated password (copy + paste) and it didn't like it. I changed it to a simple password and it took that.
