AD REALM and DNS Domain are 2 different things. 
You can have multple dns domains with other names then the REALM domains. 
But its more complex to configure.

adcli join ? 
If this works the same as msktutil 
which creates a user and sets the needed options then your real hostname and "joined_hostname" are different. 

But same here, i dont know SSSD, you might need to ask the sssd list.
