Does GDM3 lose its LDAP user list after shutting down the computer at night?

Question

linux

In GDM3, the list of LDAP users disappears after the computer is turned off at night.
If you turn it off or reboot during the day, then after rebooting or turning it on, it shows a list of users who have logged in earlier. After turning off in the evening and turning on in the morning, the list is empty. GDM takes a list from /var/lib/AccountsService/users/ and for some reason LDAP users disappear from there the next day. Somehow you can set it up without scripts that will copy this list when you turn off the computer and paste it when you turn it on.
