sysPass Version 3.1 (311.19121601) (same problem with version 312.20030701)

Describe the bug When importing users from ldap, and there are too many users in the ldap database, the import fails.

To Reproduce Steps to reproduce the behavior:

1. Setup a ldap server with 500 or more users
2. Go to 'Config > LDAP'
3. Try importing ldap users
4. Internal Server Error is returned after some waiting time

Expected behavior Users should be imported

Hello, could you please add import.ldap. to the event log tags list?. This will log any operation related to the LDAP import process.

Tried it with various settings for debug and syslog, but can't find a change in the syspass.log or the docker logs.. Where should the event logs normally appear?
