Office 365 and SSO/Passthru Authentication

[mdrabble]

I have enabled Passthough Authentication and Single Sign on within Azure AD Connect.

 

Chrome work brilliantly - enter email address and hey presto it logs in :-)

 

IE11 - wont allow anyone to sign in! It says "Your email or password is incorrect"

 

If I disable Passthru and Single Sign on then users are able to log in normally.

 

Anyone come across this before?

This is still in preview and there are some known issues and bugs with PassThrough auth so without digging into it too much I would guess you are hitting one of those potentially.
