Office 365 Prompting for Credentials when using Single Sign-On (ADFS and Directory Sync are Installed)

This is a common issue and one over looked by most administrators. Users complaining that they are still being prompted for credentials when accessing services from Office 365. This should not happen if you have ADFS and Directory Synchronization in place.

To remedy the issue, simply add the ADFS Server Farm address (sts.domain.com) to the trusted sites in the Local Intranet zone in Internet Explorer. This will allow IE to pass your local credentials to the webpage as needed.

  1. Open Internet Explorer

     

  2. Click on the gear icon in the top right corner

     

  3. Select Internet Options

     

  4. Click Security Tab

     

  5. Click Local Intranet

     

  6. Click Sites

     

  7. Click Advanced

     

  8. Add your ADFS Server Farm name (sts.domain.com)

     

  9. Click Add

     

  10. Click Close

 

Thanks for visiting and reading my posts. I am always looking for more ideas. Please comment or email me with what you would like to see.

    Hi
    Nice post!
    I did as you explained here on a terminal user. Then opened IE (10) and entered the portal.office.com site. Still I have to fill inn the username@domain.com and tab before I’m logged into Office365. Am I doing something wrong?
