After upgrading the PGP Encryption Server 10.5 or above from a legacy version (3.4.2 or older), the following message can appear:

Your passphrase is about to expire in.

There is no indication of how many days the password will expire.  This is because the Administrator password policy has been disabled in the policy and does not indicate a value.

Even if the password is changed, the warning still appears.

"Your passphrase is about to expire in."

Although the message appears, it is cosmetic and does not affect the normal use of the PGP Encryption Server.  After 30 days, the message should disappear.
