Hello, I've noticed some unexpected behavior when updating a user's FileVault password. The set up: All actions are performed in virtualized macOS 14 and 15.5 guests on a 15.5 Apple Silicon host. FileVault is enabled. sjsp is a standard user with a Secure Token. The Mac is bound to AD, and the domain is reachable. Reproduction: systemctl -secureTokenStatus sjsp shows it's ENABLED. fdesetup remove -user sjsp fdesetup add -usertoadd sjsp systemctl -secureTokenStatus sjsp shows it's DISABLED. Surprisingly, sjsp is still able to unlock FileVault. Looking at unified logs for opendirectoryd and fdesetup, I see that a password change is being attempted in response to fdesetup add, which is unexpected. default 13:34:41.320883+0100 opendirectoryd Changing password for <private> (E5CC46D7-0C1F-4009-8421-9AA8217CB784) info 13:34:41.321317+0100 opendirectoryd No unlock record exists for E5CC46D7-0C1F-4009-8421-9AA8217CB784 info 13:34:41.321331+0100 opendirectoryd <private> (E5CC46D7-0C1F-4009-8421-9AA8217CB784) is not a SecureToken user: no unlock record default 13:34:41.321341+0100 opendirectoryd Changing password for <private> (E5CC46D7-0C1F-4009-8421-9AA8217CB784): user <private> SecureToken, only new password provided, credential <private> default 13:34:41.321454+0100 opendirectoryd Changing password for <private> (E5CC46D7-0C1F-4009-8421-9AA8217CB784) with no existing unlock record info 13:34:41.321857+0100 opendirectoryd No unlock record exists for E5CC46D7-0C1F-4009-8421-9AA8217CB784 default 13:34:41.321873+0100 opendirectoryd Record <private> (E5CC46D7-0C1F-4009-8421-9AA8217CB784) is eligible for SecureToken default 13:34:41.322637+0100 fdesetup DMAPFS cryptoUserForMacOSUserForVolume DMErr=-69594 retErr=-69594 outAPFSCryptoUser=(null) default 13:34:41.322699+0100 opendirectoryd While changing password for <private> (E5CC46D7-0C1F-4009-8421-9AA8217CB784): Not adding SecureToken; other unlock records exist, but no existing unlock record provided If I disconnect the network and follow the reproduction steps then the Secure Token is retained. Reconnecting and waiting a while doesn't cause the Secure Token to be lost. There are no log entries about attempting to change the password. Any help or explanation would be appreciated, thanks in advance.
