This just started happening last week. Wipe an iPad, start the DEP/setup process and get to the Remote Management screen. It goes past the screen fine>LDAP account sign-in screen, fine> Profile Installation screen fails with "Invalid Profile"
Never had it fail 1/2 way thru the DEP process.
I have tried:
new prestage
reboot primary server
refresh token on DEP instance
Anyone else seeing this? Any ideas?
