[Samba] Computer host name vs. AD host name

Because of AD's per domain flat name space, we have a AD computer naming 
convention which kind of mirrors the OU hierarchy, so a college of 
natural sciencs machine in the Harris Lab would be called something like 
cns-khl-files.  I've run into all kinds of undocumented issues when a 
windows computer name goes over 15 characters, so that's a secondary 

Those hyphenated names are a pain for the linux users to remember, so 
what I've been doing is assigning a user friendly local hostname and 
creating a different name for AD. With sssd you can then set a value in 

   ad_hostname = cns-khl-files

and then the name defined in /etc/hostname can be anything you like. I'm 
guessing there's no way to do this with Samba, and I'm just going to 
have to reset the local hostname to match what AD expects to see?
