I have set up SSO for use with office 365 and Dropbox.
When I was testing both Office 365 and Dropbox with my domain account it was working fine.
for Office 365 I would go to portal.office.com and enter my work email address.
I would get re-directed to fs.DomainName.com and I would enter my domain password and I would be logged into office 365.
I assumed all was fine so I allocated licenses to my 20 users in office 365 but when they went to sign in at portal.office.com and were re-directed to fs.DomainName.com - entered their correct password - the page would just submit back to itself.
if the user entered the wrong domain password at fs.DomainName.com then it would give the error that the password is wrong. When the password was correct it would just post back to itself with no error message.
I cannot work out why this is happening.
any help would be appreciated.
