Thanks, this seems to be what I am looking for. However, I am not sure 
if I am reading the links right. I am supposed to make a custom 
passwd-file, and point dovecot to this?

I can use a script to parse genericstable or even virtusertable and add 
this information at the end of the dovecot-passwd-file?

And I can still use /etc/passwd as a fallback in case something goes 
wrong? As long as I keep userdb passwd in dovecot.conf?

Well, I think I should be reading some more documentation and look at 
the example configs on the wiki. Thanks for the help!
