MobileIron – replace SSL certificate

Something completely different: changing the SSL certificate on MobileIron Core and Sentry. In total, I had to replace 5 certificates. 4 certificates are replaced via the Core web interface and 1 certificate needs to be replaced via the Sentry web interface.


Within the Core web interface you have to change the certificated in two separate interfaces.

1. Login to the Core web interface and choose Services >> Sentry

2. Choose the icon (person’s head) in the upper right corner >> System Manager. Log in to the System Manager website and choose Security >> Certificate Mgmt


Log in to the Sentry web interface and choose Security >> Certificate Mgmt

The process of replacing the certificate is the same for all 5 certificates. You only need to be careful to upload the correct certificates. In my situation, users are connecting to two different FQDNs. One FQDN is pointing to the Core and is used to sign in to MobileIron and register a device. The second FQDN points to Sentry and is used for client connections from the mobile device, like Outlook Sync or Web@Work. I upload the certificate with the Sentry FQDN to the Sentry option on the Core web interface and within the Sentry web interface and I upload the Core certificate within the Core System Manager web interface.

I am using a certificate based on a full FQDN, so no wildcard certificate. The certificate’s certificate path contains two intermediate certificates and one root certificate. In total I have 5 different files:

  1. a signed certificate from the CA
  2. the private key
  3. the first intermediate certificate
  4. the second intermediate certificate
  5. the root certificate

I upload all certificates separately when choosing Manage Certificate like shown in the image.

Hit Upload Certificate when you choose all the necessary files. MobileIron starts uploading the certificates, is “smart” enough to combine all certificates, replaces the certificate for the specific service and restarts the service. This could result in a short interruption of production. After this, the SSL certificate is successfully replaced.
