ActiveDirectory

Windows Authentication is based on Kerberos standard authentication but with some extensions. Your UMIACS Kerberos5 account is different from your ActiveDirectory account and unless you set your passwords manually will not be the same.

Your ActiveDirectory authentication is used in a variety of different places,

• Logging into UMIACS ActiveDirectory Windows Domain (pc.umiacs.umd.edu) computer
• Exchange Mail Service
• VPN Service

If you need to update your ActiveDirectory password you need to access the Windows Security portion of a pc.umiacs.umd.edu domain desktop or server. This can be found in two ways,

• If you are physically sitting at the host you can press the hardware control sequence all at once

  <CTRL><ALT><DELETE> 

• If you are logging in remotely you can access Windows Security by going to

   Start->Settings->Windows Security... 

You should get a screen that looks like this,

You can choose Change Password to update your ActiveDirectory authentication.
