General settings
Admin users can define organization-wide general settings.
These settings can affect, for example, reservation practices. It’s important to handle these settings carefully, as they impact how the system works for the entire team.
Users with Editor rights to the Admin module can view this page.
Topics:
Finding General Settings
- Open Admin → General Settings.
- The settings are organized by topic areas
- Each setting includes an explanation of its function — read it carefully.
- Enable or disable the setting according to your needs.
- The setting becomes active immediately after enabling. If the change does not appear right away, log out and back in.

Examples of some of the settings:
- Identifiers → Custom identifier
- A “Custom ID” field appears on the item card. If your organization already has a unique identifier on an item (not the serial number), it can be entered here to replace the system-generated identifier in most views.
- Notifications → Notification language
- Defines the language used in Trail’s email notifications.
- Reservations → Accept reservations
- Each reservation created by a user with 'reader' rights is required to be accepted by user with 'editor' access rights. Email notifications will be sent to responsible user right after reservation was created.
- This is useful, for example, in educational institutions where teachers must approve reservations made by students.
Renewing the certificate used for Single Sign-On
Users can manage and update the SSO-SAML token signing certificate directly in Trail:
- Open Admin → General Settings.
- Select Authentication.
- Under SAML Certificate, paste the updated certificate in the text field.
- Click Save.

⭐ Tips:
- If a setting is unclear but seems useful for your organization, contact Trail Support at support@trail.fi. We’ll be happy to explain how it works.
- If your organization has multiple users, review the impact of the settings together with other key users. This ensures that each department understands how changes affect their use.
