Single Sign-On fails when computer is connected to network

After changing your Windows password, when the computer is connected to the network, the system does not log in to Windows when using the PGP WDE Single Sign-On feature. The user is required to use their old passphrase to authenticate with the PGP BootGuard and then use their new Windows password to log in to Windows.

This can occur when a authenticated user group does not have the proper modify permissions for the PGPWDE01 file on the system. If the user group does not have the proper permissions for the file, when a user changes their Windows password PGP Tray fails to update the PGPWDE01 file. Thereby causing the Single Sign-On feature to fail.


Note: This article applies to PGP Whole Disk Encryption 9.5 and above.





To resolve this issue, add the authenticated user group with Modify permissions to the PGPWDE01 file on the root of the C: drive. Logging off and then logging back in to Windows should cause PGP Tray to properly update the PGPWDE01 file. After rebooting the system, Single Sign-On should work correctly.

Changing the password for Windows rebooting the system should update the PGPWDE01 file to correct the SSO issue.
