We use https://<> for our UMP, and DNS also allows https://<hostname>/.  We would like to implement a single SSL certificate to cover both cases. How can this be accomplished?


- Guidance with CSRs/SSL Certificates


Release: UIM 8.4 or higher


The following (high-level overview) steps  are required.  For specifics, see the product documentation.

1. Reinitialize the keystore 
2. Delete the "wasp" alias from the keystore 
3. Generate a key pair, but do NOT use the command from the docs (which does not include the SAN info):

<UMP or UIM server_installation>/jre/<jre_version>/bin/keytool -genkeypair -alias wasp -keyalg RSA -keysize <key_size> -keystore wasp.keystore -validity <days_cert_is_valid> 

Instead, generate the keypair thusly (substituting the appropriate values for your domain): 

<UMP or UIM server_installation>/jre/<jre_version>/bin/keytool -genkeypair -alias wasp -keyalg RSA -keysize <key_size> -keystore wasp.keystore -dname "CN=hostname, OU=Unknown, O=Unknown, L=Unknown, ST=Unknown, C=Unknown" -ext,ip: -validity <days_cert_is_valid>

Note that you should not use "Unknown," but enter the correct values for your organization.  The Country value (C) must be a two-letter country code.

You can verify the SAN info was included by issuing the following command: 

   keytool -list -v -keystore wasp.keystore 

Here is an example result of the list command above.

#1: ObjectId: Criticality=false 
SubjectAlternativeName [ 

Next, generate the CSR using the same -ext command, like this:

<UMP or UIM server_installation>/jre/<jre_version>/bin/keytool -certreq -alias wasp -validity <days_cert_is_valid> -keystore wasp.keystore -file <your_domain>.csr -ext,ip: 

Now you should have a valid CSR that contains the SAN. You can submit this to a certificate signing authority to obtain a certificate.

Then you would simply import the resulting certificates as described in the techdocs link listed below in the Additional Information section of this article, and that should resolve any SAN-related errors as described above.
