Azure AD Sync connect error (Sync scheduler)

After adding AD FS to Azure AD connect I have som trouble with the sync scheduler.

I got status : stopped-extension-dll-extension on export for my AAD connector.

Googled it and probably the issue was related to password. After an input I created a new user in portal.office.com as an Global Administrator and figured this could be used to authenticate. I suspect I missed something here :)

When using start-ADsyncsynccycle -policytype initial  (or any other of the sync method) I get this error :

What i figure is relevant is :
multiple_matching_tokens_detected: The cache contains multiple tokens satisfying the requirements. Call AcquireToken again providing more requirements (e.g. UserId)
