Default portal subdomain being used instead of user defined subdomain in ums configmaps

We are running OpenDesk in a private RKE2 cluster based on commit 59a40864 .

We configured the portal subdomain to be used like this:

global:
  hosts:
    nubus: "od-portal"

In most places this user defined subdomain is used, however in the following places the default subdomain "portal" is used. This leads to, e.g., the user management not loading properly when accessing it from the portal. Patching these configmaps manually and restarting ums-related pods leads to the correct behaviour.

ConfigMap ums-stack-data-ums-ucr base.conf:

ldap/saml/service-providers:
    https://portal.<domain>/univention/saml/metadata
umc/self-service/account-verification/email/webserver_address:
    portal.<domain>
umc/self-service/passwordreset/email/webserver_address:
    portal.<domain>

I replaced our actual base domain with <domain>. Note that, e.g., portal.<domain> should be od-portal.<domain>.

ConfigMap ums-ldap-server:

data:
  SERVICE_PROVIDERS: https://portal.<domain>/univention/saml/metadata

Same here, it should be SERVICE_PROVIDERS: https://od-portal.<domain>/univention/saml/metadata.

If required, I can provide our values and/or other configurations.
