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

Your account might be shown in two ways,

• PC\username
• username@pc.umiacs.umd.edu

depending on the application you are using.
