I'd suggest placing the database (and the photo collection) in a directory 
where both accounts have write access (if both have to be able to modify 
data). If you have to restrict access to just those two users, you'll have to 
play with group membership and permissions. 

If you already have a database on one of the use accounts, you can test if 
access from another account is possible by changing the permissions (read 
permission for group should allow the other user to access the data). The 
other account would have to set up its version of Digikam to point to the 
database and image collection

I'm not sure both accounts can access the data simultanuously; it's not 
something I'd try with SQLite or the internal MySQL server (and MySQL support 
is still marked "experimental in GK 5.5.0). But as you talk about users 'on 
*a* linux system' I assume that simultauous access isn't physically possible, 
anyway. And according to the settings dialog the databases have to be located 
on a *local* filesystem, anyway...

Writing the tags back into the photos still means both accounts need write 
access to the image files (or even to the containing directories if you have to 
create sidecar files, for e.g. raw format files).
