Time Machine change password for account (Synology)

Hi,

I'm looking a solution to normalny change (when it expires - policy) password to account that allow me to mount my disk backup.

We using a Synology as a Active Directory users solution because we need a huge storage for backup and to automate the adding of a new user. We have too a password policy after 2 months, passwords expire and need to be changed.

Unfortunately Time Machine does not detect that the password does not match and does not try to ask you to enter a new one.

it just throws a cannot enter to backup disk and sayonara.

For this moment, solution is remove disk from Time Machine and map it again (afp://....) and add it again using previous copies.

Is there human option "change password" for it?
