Update your SAML signing certificate for Azure AD

To update your SAML signing certificate for Azure AD:

1. Before you make these (or any other) changes to your Abiquo platform, create a backup
   In this case, on the Abiquo Server, back up your config folder

   # Back up the /opt/abiquo folder tar cvfz /opt/abiquo.tgz-$(date +%Y%m%d_%H%M%S) /opt/abiquo

2. Create a new certificate following the Tutorial: Manage federation certificates - Microsoft Entra ID .  Here are the basic steps at the time this page was published

   1. Go to Azure Active Directory → Enterprise applications and select your app

   2. Go to Single sign-on → SAML Signing Certificate → Edit → New Certificate

   3. From Federation Metadata XML in SAML Signing Certificate, obtain a new metadata file and download it

3. Find the metadata file in your Abiquo platform - it will be something like /opt/abiquo/config/saml/sp_metadata.xml
   Replace this file with the new file you downloaded.
   Do not touch the identity provider metadata file.

4.  Restart the Tomcat server:

   sudo service abiquo-tomcat restart
