subscriptions via master user

Hello,

When I impersonate an regular user using master user (log in to Roundcube as "user*masteruser") - there are user's subscriptions missing. I can see all folders, but have to manually enable visibility in settings.

Is this normal? Can I fix it?

passdb { driver = passwd-file master = yes args = /filepath pass = yes }

passdb { driver = passwd-file args = /filepath }

userdb { driver = passwd-file args = /filepath default_fields = uid=vmail gid=vmail system_groups_user=vmail home=/srv/vmail/%d/%n master_user=%u }
