Extension:PIVLogin

The PIVLogin extension will enable PIV card authentication similar to the way Window OS authentication via PIV to Active Directory. This is compliant with US Federal Government Standards regarding HSPD-12.

This extension utilizes the value of subject alternate name in the PIV card to authenticate with Active Directory. The value of user principal name in Active Directory has to match the value of the subject alternate name in the PIV card. This extension fetches the subject alternate name from the PIV card bypassing php bug 60388 which normally prevents this.

This PIVLogin extension was developed by the Division of Information Development - IAIT - ASIA - Bureau of Indian Affairs for use on the Department of the Interior internal Wiki.
