Hi We are using Koha 24.05 and are intending to use a LDAP server to fetch the patron data for Koha. During the patron login process Koha will fetch the patron data or update them. So far so good. But what happens if a patron is no more existing on the LDAP server and does not log into Koha anymore? As we understand the once fetched data will just stay in the Koha database (in tables "borrowers" or "deletedborrowers") forever which conflicts with requirements of privacy. We imagine we could regularly compare patron data on the LDAP server with the patron data in Koha (using SQL reports); or we could just regulary and manually delete Koha patrons that expired in a given period and don't have no loans etc. anymore (e. g. using the batch patron deletion tool); but such a manual process seems cumbersome and error-prone. Script "cleanup_database.pl" does not cover patrons. Thus the question: Is there maybe a best practice how to get rid of patron data in Koha that do not exist on the LDAP server anymore?
