User migration
Gibraltar 2.5 has a new LDAP-based user management. Therefore the update process has to transfer existing users into LDAP. It is not possible to maintain all users passwords - HTTP- and SMTP passwords will get lost during this process. Gibraltar will generate random passwords for these users. You can see the result of the migration process in ("Configuration management" - "Save configuration" - "Download migrated users").
