# HARICA Certificate Manager Guide

This source provides a detailed operational procedure for requesting and managing server certificates through the HARICA Certificate Manager for the Universität Greifswald.

## Key Procedures
- **Request Process**: Users must log into the HARICA system, navigate to the **Server** menu, and specify the desired domain names.
- **Validation Type**: The guide specifies using the **Domain-only (DV)** type.
- **Submission**: The process requires the manual upload of a Certificate Signing Request (CSR) via the "Submit CSR manually" option.
- **Approval**: Certificates are not issued immediately; they require approval by the [[universitatsrechenzentrum-urz]] before appearing in the "Valid Certificates" section of the dashboard.
- **Retrieval**: The URZ recommends downloading the resulting certificate as a **PEM bundle** to ensure the full certificate chain is included.

## Technical Constraints
- **Domain Limit**: A maximum of 20 domain names can be included in a single certificate.
- **CSR Handling**: HARICA ignores any DNS information contained within the CSR itself; domain names must be explicitly entered in the manager's interface.

## Support
Technical issues are handled via the [[universitatsrechenzentrum-urz]] through their hotline (ext. 1420) or the [[groupware]] ticket system.
