I though a little bit and I do not understand
what do you want to achieve?
The behaviour which you described here is expected.
user(a)transmode.se and user(a)infinera.com are two different users for sssd.

That was a typo on my part(directly from memory ... getting old :)
I have
domains = transmode.se,
infinera.com
Now transmode.se is default and if I switch to
domains =
infinera.com, transmode.se
Then
infinera.com is default

Yes, I have that one too, one for each domain

So it seems which is confusing, why will not sssd listen to default_realm ?
maybe you did not get a message from previous mail.
domains in sssd.conf cam be anything(default,test,LDAP ...).
man sssd.conf says:
domains
A domain is a database containing user information. SSSD can use
more domains at the same time, but at least one must be configured
or SSSD won't start. This parameter described the list of domains
in the order you want them to be queried. A domain name should only
consist of alphanumeric ASCII characters, dashes, dots and
underscores.
It is just a convenience to use dns domain name for IPA and AD.
That's the reason why sssd does not know anything about default_realm.
It is a totally different option in different configuration file.
