Office 365 federated users, locked out
A brief overview of my stupidity.
Setup a new domain on 365 using the domain.onmicrosoft.com approach, worked great
Verified my real domain.
Setup dirsync, great
Changed UPN on users to real domain.
Setup active directory federation services 2.0, stupidly migrated my only admin account to a federated setup before I got single sign on to work. Now I can't login to the admin portal because it wants me to use the new federated login page which I don't have working. How can I disable federation so that I can login bearing in mind that the account was used for dirsync and PowerShell so I can't use either of those tools.
I know should have ha multiple admin accounts but hindsight is always 20/20.
