File Share Encryption

Hello,

I need a help with the following issue:

I have a customer who is using the PGP removable encryption feature and when he encrypts the pendrive, the passphrase that is used to protect is his AD password.

Its great because the user only need to memorize one password to logon on WDE and decrypt the pendrive. 

The issue happens when the user change his AD passphrase, the PGP doesnt sync the new AD passphrase with the passphrase that is used to encrypt the pendrive, therefore the user needs to use two different passphrase.

Is there anyway to use or to update the passphrase with the AD passphrase after the update?

Are you sure the's encrpyting this pen drive against his AD creds and not just deliberately using the same password for both?

I believe he is taking the AD password like WDE, where can I check this information? An option in the interface? 

Thanks in advance
