Server 2019, OMSA 9.1 dosn't work with IE

I installed OMSA 9.1 today on several Server 2019 machines. The IE in Server 2019 blocks the access to the web client because the certificate is invalid.

How can I change the certificate? We have not our own CA, we get our certificates from an external CA.

Hello

I'm not aware of any version of OMSA that is supported on Windows Server 2019. You can try adding the site to your list of trusted sites and reduce browser security to get it to work. If you want to perform certificate management within OMSA you will need to be able to load the web page. The Preferences option in the top right of the web page will allow you to configure local settings like certificates for OMSA. You can find more information in the documentation.

Hi,

thank you for the hints.

For the moment supports OMSA 9.x no Server 2019. But 2019 is out now end will be very quickly adopted I think, in every case by this organizations who migrate from 2008 R2 directly to 2019 (like we). So I expect that OMSA must support 2019, even if it's not official now. ;-)

But back to my question: It seems that I can import a server certificate in .pfx-format. But our CA accepts only FQDNs in the Certificates, no NetBIOS name. If I start OMSA via the desktop icon, the default is https://servername:1311. With this I have still a problem, because the certificate contains only the FQDN of the server.

If I change the address to https://servername.ourdomain.tld:1311 all thinks are fine.

How can I change the configuration of OMSA so that the default is the FQDN?

Greetings Barbara

You should be able to set the URL behavior using OMCONFIG. I don't know of a way to do it from the interface. This should be covered in the OpenManage CLI guide. It is on page 100 of the OMSA 9.2 CLI guide. You can find the CLI guide on the OMSA support page.

Hi,

 

nice idea, but unfortunately it didn't work:

C:\Windows\system32>omconfig preferences webserver attribute=seturl host=myserver.mydomain.tld port=1311
URL configuration is not supported because Server Administrator web server is present on this system

It seems that omconfig is not able to change the configuration of OMSA. I hoped that I must only change a config file using a text editor. But I couldn't find such file.

My work around is a classic desktop shortcut with the correct URL as link.

Greetings Barbara

The OMSA development team advised me that the seturl option is not for local installations of OMSA, it is for applications like OpenManage Essentials. I did some more digging and found another method. I tested this one, so I know it works. You can modify the server.xml file found at default location: c:\program files\dell\sysmgt\apache-tomcat\conf\server.xml. It is line 83 in the version of OMSA I was testing with. If you add address to the list of variables in this line then you can input any variable you want to go into the address field.
