Installing catworkx LDAP Custom Field Mapper requires configuration changes on the Jira system. Changing the configuration can effect the running system. This can be – for example – the unintended appearance of issue types in the "Create Issue" dialog or the appearance of fields in the create or edit dialog. To avoid these side effects, you probably have to adjust your current configuration (e.g., replace the standard issue type scheme by a project specific scheme).
In any case it is recommended to install a new app on a test system first and check the critical dialogs.
