[Koha] Import in koha 21.05 all users from LDAP

Hello, We have Koha 21.05 installed and configured to work with AD. Everything is fine, users can login to Koha using AD credentials, but in Patron list they appear only after successful authorisation. It is quite annoying, because if you want to assign book to the reader, he/she has to be in patron list. Is it possible to create Cron job to import users to patron list automatically from AD (it is enough to import only a few fields, all other fields can be updated after user login)? Thanks for the answers
